Over the past few months, the Twitter bandwagon has been getting increasingly crowded. This has caused an exponential amount of noise - good and bad - within the Twittersphere, and a growing amount of chatter about Twitter.
I have little problem with noise. Following doesn't have to be a mutual thing. There is NO obligation to follow those who follow you. I never auto-follow. I'll only follow you back, if I think your stream looks interesting to me, and if I follow you, and you don't follow me, then that's fine too.
I find it's quite childish to get those that unfollow you within a few hours simply because you didn't follow them back.
Just because you like to read my tweets about green widgets, because you're interested in them, doesn't mean, I find your tweets about red balls equally so.
"All these problems are nice to have because they’re growing pains. The challenge will be creating tools that meet these pains. Two areas that might get a lot of attention in 2009 from third-parties may be noise filters - services that intelligently eliminate inane updates (e.g. remove any mentions about lunch or coffee”) or smarter, easy-to-create groups."
