I prefer the usability of the OPs much better. The use of dollar signs might be a little clunkier than the begin/end tags when you want to use a dollar sign. But all in all I think the presentation is better and a bit more welcoming.

Yes it is, and I hope he can contribute to mathbin as it is more widely used - at least it's official pastebin in ##math channel on freenode.

I don't know if the author of mathbin is still working on it (the message on main page is old), but I think it's worth a shot ;)

I showed this to ##math and the ops decided to make TexPaste the official pastebin instead of Mathbin: http://i.imgur.com/hk9fPZV.png

I disagree about dollar sign. This is how embedding mathematical notation in LaTeX always worked, and I never had, nor heard of anyone having problems with that in practice.
