Search for a popular forum about something you know a few things about.
Make an account, edit the forum profile, can put up an avatar.
The trick is to add a link to your weblog to the footer of each one of your forum posts like so:
Then you only have to answer 2 to 5 questions per month to get noticed and indexed by google.
Just spam the forum with answers as much as you like, each post you make is a link to your blog. People search forums for answers but most are to lazy to answer any. If you help a person he or she may check out your blog.
I think this is a fair and good way to get some links, it is kind of busy in the blogosphere you know?
