What area should I start working on in Internet Marketing?

I am 24. I play guitars (advanced) and the piano. I am good at programming and puzzle solving. I am pretty much everything a perfect computer geek needs to be. I am planning to start off a company before which I will need to get a feel of how marketing works on the internet. I would like to create niche blogs but I don’t see where I should start and what topic would be ideal for me. Could you suggest a way for me to get things going.

Surely there are lots of ways on how to start internet marketing. You can start having your own free-hosted blog and write worthwhile contents that you know. You may start exchanging links with other bloggers and link partners. You may also do bookmarking and join internet marketing communities. Be able to know good ways to spread your blogs throughout the web.
