No mention of Techmeme? I'll add that the best way of getting picked up by other bloggers is first Techmeme (not the largest audience but definitely the most influential in tech) and second HN.
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
+ 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
Good advice. I wondered why/how I got included on Techmeme before. I would assume it is based on "Techmeme can discover stories based on retweet counts,".
TM takes hints from a lot of sources - including HN. It has 30k+ sources that it directly crawls itself as well, and uses a lot of different hints to work out what is popular. The biggest hint to a big story is inbound links from other blogs that are also sources, and from there things like popularity on social media
I have never submitted my own posts to DZone, but they have been submitted by others. It isn't in my top10 referrers. My impression is that most of the audience there is Java developers looking for technical posts
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+.
