Say a twitter account is listed x times.
So what, you might ask.
Indeed, the absolute number means little.
But by observing both numbers as a ratio (followers to lists, F/L for brevity from now on), I think I have found a quite meaningful use of them.
If a twitter user is performing some sort of broadcasting of news, offers, weather, traffic, stock prices etc, it might useful to follow. But doing so in the timeline breaks the convesation and de-humanizes the stream.
Following such users/accounts through lists is much more convenient, much more practical. It brings sanity to the timeline.
If my assumption is correct, then such users/accounts would be listed relatively more often, than followed. Hence, the F/L ratio would be relatively lower.
This metric, if true, can be used for identifying and classifying an unknown (to us) user.
My guess is that if the ratio is less than 10, then this user/account is probably a broadcasting account of some sort. Or his activity is such (: publishing own blogposts, without engaging in conversations).
What is your F/L ratio?
