Would it be possible to have a search box on Activity subpages -- in other words, a search function that limits itself to a single user's comments or posts? [more inside]
How about a MetaFilter user survey about some of the ideas that have been bandied about in MetaTalk lately: recommending or rating posts, enforced posting delays, giving better posters higher posting frequency, etc.
Now that membership has opened again, how about greeting new members on the front page just after they've joined with something like, 'Metafilter welcomes [insert link to username and profile'. It's always good to get a hug when you arrive at a party.
Courtesy of Aaaugh!'s mad GIS skillz, every metafilter member with a zipcode in their profile has been plotted on this map [inside]
Thread/Comment and User Growth statistics are up for July. This is the first month that threads and comments actually dropped slightly, largely because new user signups are still disabled. Also, we broke 10,000 user IDs yesterday. Congratulations, Ricci.
