I've read that you can get your site or Web 2.0 properties indexed (quickly) if you post their links on Twitter. Personally, I don't believe it. Has anyone heard this???
There's nothing magical about Twitter. In fact, if anything Twitter is probably less beneficial than links in other places because of the "short" URL requirement and the resulting lack of anchor text.
If you place a link to your site or page anywhere on the net, spiders will find that link and follow it. If you can do it on a well-spidered and well-indexed page, like this forum, it will happen that much faster. That's what spiders do. It's ALL that they do.
Sharks do nothing but swim, kill, eat, and reproduce. They are master machines at doing those things.
Similarly, spiders follow links and send back data to search engines. That's all they do. And they do it masterfully.
