Seriously though, good post. Twitter noise is something I wrestle with every time I open up my TwitBin (notice the use of Twitter lingo). My thoughts? Unlike other services meant to help you find the most relevant and most pertinent bits of info, I have found the best tidbits via Twitter to be random. As long as you build a community on Twitter of people engaged in activities that interest you, the discussion should be relevant. I never worry about back tracking (okay, occasionally I’ll go crazy and back track to see if some well-known Twitter/blogger extrordinaire (Paul Bradshaw, Anastasia of YPulse, etc.) or if a friend or coworker has replied to me, but MOST of the time, I count my losses. I don’t RELY on Twitter for info. I count on it to sporadically enhance the information I get with links I might not have found and info I might not have gotten otherwise. And I have to note, there is an element of community–a feel-good feeling (redundant, I know)–that comes with Twitter. It’s there if I need to vent. It’s there if I get stuck with a problem and I need to ask for help, and it’s there to provide me with the random treasures of info when I’m sick of all my highly-focused and targeted vehicles.

Of course, all of that is not to say one couldn’t set up a Twitter for a specific community of people with the goal of keeping it relevant–a group of coworkers for example, who use it as a project management tool; or a business/organizational entity who might, as you said, see fit to hitting the sweet spots for their audiences.

Glad to have you join my subconscious stream of randomness that is my Twitter feed. :)
