One of the things that you are told about Twitter by those "who know how to use it properly for business purposes" is that you are supposed to follow everyone that follows you on Twitter.
I am a bad Twitter user. I follow most, but not all, of my Twitter followers. This may be because I am more prone to looking for story and article ideas, along with a few mintutes of entertainment than trying to run a business from Twitter.
Instead of giving you a list of the type of people I follow, it would be easier to tell you who (what) I won't follow on Twitter---tweets in languages and characters that I do not understand (Chinese and Russian mainly), machine-driven spam tweeters, and people who are going to tell me (loudly) that my religion is wrong.
The one I can look at and see that it is in a language I do not speak or read. I do follow some French and Spanish tweeters (I was surprised to learn that I could read some tweets in Spanish). The other is based on fair guess---if you sending out articles links detailing Christmas gift ideas in July, I am guessing that you are actually a machine. The last is typically loud Christian Republicans who openly state that all Wiccans (Witches) and Democrats should be burnt at the stake---you can hardly miss spotting them as they try to set you on fire.
I will admit that I do have a few people that I follow who fall into these categories. For instance, I do follow a few tweeters who use robots to tweet, but occasionally they (the real human being) comes along and posts something that looks personal. But most robots I ignore. The other categories also have their special cases---entertain me and I will follow, no matter how dubious your personal habits or the related language difficulties are.
Now I will admit that I have some weird tweets coming up---I have an article up on Associated Content about listening to Christmas music in July. But the article is actually meant to be read in July (or December if you are into Christmas music).
Anyways, if you follow me on Twitter and I do not follow you in a 48 hour period---this is probably why---you are a Pagan burning and bashing Christian spamming robot.
As always if you have discovered an useful reason for following everyone, even people you do not understand, please feel free to leave a comment. Remember it may take me up to 48 hours to get back to the computer and approve comments, and that I send spam and flames directly to the round pixel file.
