I have an Adsense account, what are the legal ways to promote my site?

My opinion is to use Social networking sites like Orkut, facebook etc. Mylot is also good place, but most people here just keep an eye on their earnings only, so you may not get good traffic. By the way, I just visited your blog. It's wonderful. If you can add some info on travel facilities & accommodation, your blog would be still better. (But, try to make it short)
