Do Link exchanges with related sites. Post comments on related blogs. Whip up interesting posts- posts on which people feel inclined to comment and give their view. Have a good URL structure, make your blog easy to navigate . Buying links with your desired anchor text will obviously help
along with the usual site seo you should also join blogging communities like technorati and mybloglog
Definitely. Don't forget to get out there and participate in other people's blog communities. People are much more likely to link back to your site if you've become involved in their discussions. Of course you need original content too, but don't forget to comment.
Aaaaaaaaaaand, last, but not least - start a contest on your blog, or invite a guest blogger to make a few posts!
Stumbleupon is my favorite for large amounts of traffic. For seo though just posting on a large variety of popular and small blogs plus having others comment on yours will increase seo greatly.
link exchange just make sure its a 3way, or a simple method is getting a load of posts on forums and putting you're link in the signature.
Blogrolls and rss feed submissions, i promoted my video blog via rss feeds at first, they helped me so much.
Get back links to everything you do, your main page, post pages everything. For your main page one thing to do is search on google "your keywords" and many variations of "submit link" "submit site" add your link" "submit your site", should bring up lots of related places to drop your link. For your posts, social bookmark em, netscapes good for some high PR back links for your posts.
