@darius I tend to only follow people who I wouldn't mind reading 100% of their tweets. So I've always made my bots post once or twice a day instead of the common once an hour or so - I don't want them to babble constantly. Little robots I program to leave me a present at an appointed time to help me mark time and make it through the day.
@jplebreton yeah unless I have a very specific reason, I make my bots post 3 times a day -- I would do less than that, but then I would end up with people in certain time zones who would never be awake to see the posts
