I'm thinking about setting up a blog all about internet marketing including a few things about SEO, setting up sites and so on. The only thing that's putting me off is that I have a feeling that there are already too many sites that do this sort of thing(maybe there's not?), so is it worth it? One of the main reasons why I'm thinking about doing this is because I'm starting to get tired of "normal" micro niche type of sites. Plus I think I've more of an interest in this sort of thing rather than something random so it might be easier for me to keep the site updated regularly.
