No catch, I started the website as a free resource of LaTeX templates because one didn't exist and I intend to keep template downloads free. All current templates are licensed under creative commons. I do have a few plans for how I can capitalize on the website but templates will always be available for free download and I despise ad-ridden websites so that won't be happening either. If you have any ideas send me an email!
It is getting more and more popular and I am making a little bit of money from it, but it is primarily for the masses. If you like the work please consider donating through Flattr, or better yet, take out an advertisement ;)
NOTE: If you do decide to build your own thing, I think it would be cool if you could run LaTeX in the browser directly (I guess you could do this by building pdflatex with emscripten)
Thank you. Do you know how they did the "intros" -- the dark overlay with popups that point out various buttons / explain concepts? Are they using intro.js, something else, or something they made themselves but haven't released yet?
Also, could you provide more detail about what you mean by "run LaTeX in the browser directly"? It sounds like a fun challenge.
"run LaTeX in the browser directly": Right now it appears to send data back to their servers to compile every time. What would be cool, especially for offline work, is a pure-JS implementation of the rendering engine.
Unless forced to do otherwise, I always use the memoir document class and compile with xelatex. I've found that to be the best way to get access to fancy features. What about you, who do much more advanced stuff, is that something you use for your templates?
Typically, people print large posters at places like FedEx Kinko. Converting color posters to B&W ones, although sound trivial conceptually, sometimes poses a practical challenge. One is you don't exactly know how the color posters will look in black and white.
