Nice post on some things to do and not do on twitter, and Why Your 4,243,564 Twitter Followers Don't Mean Jack. Speaking of which, these people who follow thousands and thousands of people I don't understand, there's no way you can read or get any decent content from all those people, and quite frankly it's just annoying because I know you're not following my tweets (at @arcterex) because you care about me or what I have to say, you're just absorbing me into you mega-twitter feed for your SEO (or TEO?). Meh.
Ironically I got this link from looking at one of those people's feeds while trying to see if they were all SEO spam or random links or not :)
