If it's news, I pretty much write it and forget it, news engines take care of making sure someone finds it.
If it's
blog stuff, again google
blog's will get it indexed pretty fast, and i'll probably get a few b-links from the rss feeds. I will though, first add a couple links to my other inside pages from the article, especially if i'm following up on something that already happened.
I'll go through it add some keywords and tags, as Kaus said above, same with my static pages... then I check my keywords for percentages, because I can get carried away.
If I think it's 'catchy', like controversial, or something people are going to be excited to read, I digg it, or stumble it.
The last thing I tend to do, which should be the first thing.. is read it outloud, generally because my husband or someone wandered by, and I want them to hear it.. when you read outloud, you find all of those crazy little errors.. so i edit .. errrm about an hour after publishing :O lol
