would a logo for a blog count as commercial use?

If the blog is a private blog: No
If the blog is a company blog: Yes.

right. its like getting blood from a turnip when you want people to kick down some cheese for a font.

Welcome to the sad side of the font-business. Everyone wants to use nice new fresh fonts. But no one wants to pay for it. It’s like the people think that fonts grow on harddisks and they were done by software or machines. They are not! Each letter is done by a designer, each letter was drawn by hand. But this fact people don’t like to hear.

thats pretty much graphic design. someone hires you then tells you to do it their way. The way you've been trained NOT to do and then they freak out when they get the bill.
