So, I've begun tweeting. I like it. It's a lot to keep up with, but I feel like I'm reaching people and finding new people in a way I never would have otherwise. Here's my problem: my followers are incredibly fickle. For example (and these numbers are not exact, they're just an example):

Monday- 110 followers

Tuesday- Three emails saying "______ is now following you!" so I should have 113, right? Wrong. 109.

Wednesday- 5 emails saying "______ is now following you!" but instead of 114, it's 112.

Thursday- 108

Friday- 113

etc, etc, etc.

Is this normal? Is twitter always a roller coaster like this? Up and down and up and down? Or am I doing it wrong and therefor driving away followers?

Give me advice, give me your stories, let's really talk about twitter!
