I had an interesting twitter discussion with The Masquerade Crew on twitter this morning (@MasqCrew).
It cantered around the use of twitter, and it boiled down to 'Is more followers always better?' and I have to say the answer is unequivocally no.
Some users follow thousands, or tens of thousands of other users. If you tweet that becomes just one message among a huge list, and given that twitter shows only the most recent tweets on login then unless you have directed it to them personally it won't get seen. That sort of follower has a very low impression per follower %.
Conversely if a user follows say 20 people at the bottom end i.e. someone active but with a limited twitter sphere then they'll almost certainly have your message in their feed. This means that the % impression per follower is much higher.
We also noted that some users RT, mention and favourite far more readily. You guys are worth your weight in gold. If I have, as a purely theoretical example, 10,000 followers. Ten retweet me. Not all those RTs are equal. Some users have more followers than others (obvious I know) but of those there is likely to be a shared following. Those guys are a 2nd impression on the same person, which may or may not be a good strategy. Others will have followers with busy feeds that just won't see the RT.
E.g. the tweetreach for MasqCrew, http://tweetreach.com/reach?q=@MasqCrew shows that they reached 64,058 accounts with 96,474 impressions.
Of these 28,772 came from one tweet by @Waldeez1, another 11k from @rsguthrie, 9k from us (@90daysnovel) and 6k from @zanebradey to mention a few of their biggest impression generators.
In total 90,000 of their 96, 474 impressions were generated by just 18 users, and the bulk of it from just 5. These followers are the facilitators that let them get their message across. I'd settle for a few hundred Waldeezs over ten thousand 'barely log in' twitter followers any day.
We also noted that the ability to interact reduces as we follow more. A few hundred follows can all be interacted with a little. A few thousand cannot. It's a pie - and the smaller the slice the less of a relationship you build with your following / the more time it takes to maintain the same level of involvement. I said it before, and I'll say it again - twitter is about relationships not content dissemination. You aren't broadcasting an ad, but building a fan base (and becoming part of others fan bases). When we forget that, and follow too many, people start to unfollow.
