Twellow-A directory of Twitter profiles

Just got done searching and getting to know Twellow, a Twitter Directory.  It's free to register and you can claim your Twitter profile.  It's great to find people to follow in categories that interest you.  If you're a jobseeker, you can follow companies, consultants, and nonprofits.  If you're a nonprofit, you can get listed in activism, volunteer and other categories.  Looking for venture capital?  Follow some VCs. Find out who's in your Twellohood (people who tweet who are geographically near you).
