what is with the 'donate' button?

What is with the donate button on blogs? If you are going to blog and give out information, why would you then ask for money for something that you are giving away in the first place. Sorry for all the italics. I know it is not good writing, but I am irked. The donate button to me is like the passive-aggressive tip cup at the counter at Starbucks. You are so put upon for having to do this dead end blog. You are not being properly paid for your time. Obviously you are oppressed by your oppressors. What's that? You are self-oppressed? Being self-employed, I find this particularly annoying. Should I put up a donate button on elaineperlov.com?

I thought the whole point of blogging was self-created self-expression. Information about topics you feel passionate about. Special talents you may have that you want to share. That's why I do it. That is why I run my company. I don't bring a tip cup to trade shows when I show my line. So just give, give up your whiney mind-set, and feel good about giving. It will make you feel better! That is my 2 cents. This is the entry that sparked this entry.
