I have been a blogger for over five years.
I suppose the first question that needs to be answered is — why do you want to blog? Do you have a particular interest that you want to blog about? Do you have viewpoints that you want to express? Do you want to blog anonymously or under your real name?
Once you determine what your goals are, you should be able to determine whether or not you should blog.
You have to determine the reason that you want to blog. What type of blog do you want to have?
As for making money — yes, it’s possible to make money off of a blog — but you have to put a LOT of work into it. The amount of money I make off of my blog is less than $100 a year — but then again, I’m not blogging for the money — and therefore, I don’t put as much effort into my blog as others put into theirs. For me, it’s almost an afterthought and if Google closed down Adsense tomorrow, I’d still continue to blog.
If you have specific questions, I’d be happy to answer them here or via email.
