It's been a good month: I'm about to launch http://workwolf.com : an online marketplace for parttime and odd jobs (which, for various reasons, I feel just does not exist)
I've also had a number of conversations recently on the state of academic publishing and how it can be improved, so I put together a reddit-based interface to the arxiv pre-print server, where hopefully people can now discuss up and coming papers and let the cream naturally rise to the top: http://arxaliv.org/
I'm also a developer on http://lmfdb.org/ but that's a rather technical site for research mathematicians.
