Blog a new way of earning, but how??

Personally, I think that blogs are the way to go right now. I say that because generally, with a blog you update the content quite often, preferably daily. Not only does that get you a higher rank in the search engines, but it keeps people coming back for more. The real important thing is making a name for yourself, how many people know you and read your blog every day? Your opportunity is pretty much controlled by your publicity, the more people check out your page, the better the chance that somebody will find one of your links useful. Hope this helps!
