Very true - this is why I finally removed all my social bookmarking activities from my Twitter stream and now I only stick to posts from my blog, my own messages sent to my followers, discussions with people I follow, and some cool finds that I want to send some Twitter love to.

But whatever you choose to do on Twitter, the best part is that the community will decide for itself: eventually you will see that if you do not post anything interesting and only use Twitter for self-promotion, people will just stop following you or will stop paying attention which is not better.
