There have been several similar efforts on HN recently; search engine for blogs, recommendation platform, etc. What is the number one problem you are trying to solve? Maybe we can join force and make a better platform together.

For example, my pet peeve for HN is that they don't send emails, so I have to check back here. So, my project is exactly about that: Your comment should be send back to you and the one you rely to, in full text with basic markup, with proper email threading maintained.
