Twittering Egotists, Spammers, Reciprocators

Despite only ever posting two tweets, I have nonetheless found myself with seven followers. Do these followers really care what I have to say? Of course not; I doubt there are seven people in the whole world who care what I have to say. Instead, as I have no 'friends'(whichever meaning of the word you take) on twitter, my followers (and probably the majority) fall into three categories: Reciprocators, Spammers, Egotists.

Reciprocator: Those who follow you because you are following them.
Spammers: Those who follow you in the hope that you not only follow them, but buy whatever it is they are selling.
Egotists: That special sort of individual who is trying to sell themselves.

As with any classification system the boundaries are not particularly clear. A Reciprocator (mine is the infamous Scoble) may actually be an Egotist where you have got in there first. On the other hand I am not sure whether my latest follower (Jason Calacanis) would be best described as a Spammer or an Egotist. Is he selling himself or his company? Whilst I must admit I admired the ingenuity of the first Spammer I came across, it is a ploy that only worked the once, and now I don't always look to see who my new followers are.

Digging, Reddit-ing, Stumbling, and Tweeting this particular post, should satisfy my own egotism without following 16,000 others on Twitter.
