What they offer?

You can purchase WordPress, HTML/CSS, Tumblr, PSD , Email and Magento templates.   They do have a link to a "more " section that currently has nothing under it, so I assume they are planning on offering more in the future.  As of right now, the selection is pretty small, but in time I am sure that will change soon as people find out about the site and their templates.  The templates they do offer seem pretty well made with the high quality designs you expect from an upscale market place like this.

What's the same?

A lot of the site is the same as ThemeForest.  Most of the categories, the quality of themes and the overall structure of the site is very similar.  One thing I have noticed is that the organization of Mojo Themes is a lot better than ThemeForest and I personally like the design of the site a lot more.

What's different?

The first thing I noticed is that they don't have a "friends" feature built in,  which to me is great.  So many sites now-a-days have social networking features built into them, when it's out of place and not needed.  I have friends on facebook, which makes sense.  On a site like this, it's really just a pain in the butt and to much time out of my day to build up a friend list.

Like I said before, things seems to be laid out better and in more user friendly locations.

One more thing...

I had to throw this two cents in before I finished.  The support for the site is awesome.  I emailed these guys at almost 1am and got a reply in less than 5 minutes and they were super nice.  I then made a suggestion about the site and they literally changed it on the spot, right away.  It's hard to find really good support like that on the web and I was very impressed.

In conclusion

Overall, I hope this site takes off because it's really well done.  Hats off to the founders JR Farr and Brady Nord for doing such a great job creating the site and I wish you the best of luck with it.

Also, I would like to point out that this is a totally unbiased review and I was not paid or contacted by mojo themes to write it.

BustAName

This app is hands down the greatest tool I use when looking for a new domain.  It has so many amazing features, but just listing them off here doesn't do it justice.  You really should go try it out for yourself, it's free and you don't have to signup for an account.

BustAName has two great feature, the first being that you can just type a domain in and it will tell if you if the .com, .net or .org are available.  This is extremely useful when your brainstorming or trying out variations of  word.  The other great features is it's ability to combine words in a list into into two word domain combinations.   Each word in the list has it's own thesaurus for finding synonyms which comes in really handy for finding even more variations that you didn't wouldn't have come up with on your own.   This is really just the tip of the iceberg with this app, you should absolutely  go check it out.

Domain Pigeon

This site is sort of hit or miss, but I like the concept of it.  It takes a lot of 5 letter or less gibberish domains and lists them all in one place.  Most the time, the domains listed are crap, but every now and then you see something that is actually good.  A diamond in the rough.

Domainr

This is a clever little tool to help you find domains like: del.icio.us.  These domains can get out of hand fast, so you have to keep it simple and creative when choosing one.

Nettuts+
Probably my favorite site on this list. Nettuts+ has a ton of useful information and tutorials. A great place to get your jQuery fix on.

Noupe
Noupe is a just a staple resource if you are designer.  It's a super quality site with a ton of good tips.

1stwebdesigner
If you like lists, then this site if for you.  Focused a lot on design and wordpress, I've gotten a lot of good information from this site.

Smashing Magazine
Just a good all around web design blog.

Six Revisions
A lot of good industry information.

CSS Tricks
This site has a ton of resources available for you.  They have great articles, freebies and a good code snippets section.

Smashing Apps
This blog has some good posts covering a wide range of topics, that keep me interested.

Amy Editor

Amy Editor is a really nice online IDE that is designed to look like your working on a Mac.  It has tons of features, including online corroboration and support for a ton of syntax's.  At the time of this article a few of the features weren't really working, so hopefully they get them straightened out soon.

phpanywhere

phpanywhere only works with PHP, but it is really nice editor.  It has all of things you are looking for in a good PHP editor, like syntax highlighting,  line numbers, support for projects and also a really impressive ftp file editor.

CodeRun

Coderun has some nice benefits, like not having to signup for an account and the ability to just preview / run your code right away.  It  reminds me a lot of Visual Studios, which doesn't give me that happy feeling all over, but maybe that's a bonus for you.  Seems like it has a lot of support for ASP type stuff, which I am not into so I can't really give a good review of that.

Kodingen

Where to start with this site?  The first thing I would do is watch their demo video, which is really helpful and shows you how powerful this app really is.

The site has a pretty crazy design , which can be good and bad, it really just depends on your preferences and whether you like it or not.  You can work on things as a guest, but the real features are only available if you signup for an account.  They have one click installers for a lot of popular applications which is nice.  You get your own preview / demo url and they have a very powerful ftp tool.

Bespin

"Bespin is a Mozilla Labs experiment on how to build an extensible Web code editor using HTML 5 technology."

HTML 5 is cool, but right now it's not supported in a lot of browsers.  Eventually this will change and i'm sure a lot more apps like Bespin will appear.
