+ Attach yourself to a story cluster if a relevant one is already there by linking to a source post
+ `tip @techmeme <url>` on twitter
+ Message the editors on twitter
+ Make sure your feed validates, can be autodiscovered etc.
+ Techmeme can discover stories based on retweet counts, so make sure the same canonical URL is being retweeted and favorited from the post, from twitter, disqus etc.
+ Post interesting things frequently enough that you become a source that is crawled by Techmeme
so what about dzone?
Being the first to submit it to delicious is also a good idea, with good tags. Whoever submits it first their title will be the prevailing title for the post with future re-posts, so it is a good idea to be the first to do it and set your own title before somebody bastardizes it (this is the reason why I submit my own posts to HN)
Submitting to Google+ is also a good idea since it is a very good way to get the Google crawler to visit the page and index it.
My own routine after I publish a post that I think may be interesting to others is HN, twitter, delicious and Google+.
I've had blog posts pick up their traffic peaks 2-3 days after they were posted as the route was techmeme -> other tech blogs -> mainstream media
