A blog would offer a few other advantages: 1. If anyone is ever looking for something similar to your side projects / hacks, it would likely turn up on a Google search and direct it to your blog. I don't think search engines give as much priority to social news sites. 2. If you do end up meeting people who are into what you're doing, they can subscribe to your blog via RSS. It's much easier to follow someone that way than to wait for a posting of theirs to pop up on a site like HN.
