If I had the time, I rarely go on blogs though. I think a really interesting blog would be the type of blog that gives you basic coding that you can put in your Notepad to make things happen, like making your computer say something you type in, etc.
I might, but it would have to be good and regularly post up to the minute news. I visit Mashable and TechCrunch every now and then. Try and think of ways that you can differentiate your site and make it better than them.
Probably not unless you can set yourself out to be unique and just different to the big blogs, with 10+ writers contributing daily with genuine flood of comments to discuss with.
