Sorry for the problems with the site, recently. Wordpress was having some database problems — some plugins were overloading and not everything was up to date.
Apparently, some worm was being propagated on my host's server because of some out-of-date software, causing the site to go down for a day or so.
Everything has been updated, though, and I've actually re-installed Wordpress to make a cleaner database.
Hopefully the site should be working fine for you. If you notice any problems, please let me know.
On a side note, I'm considering a new Wordpress theme — have any suggestions?
