I am not affiliated with YCombinator, or the excellent SearchYC.com.
Hacker News is a brilliant source of news for any programmer who wants to be an entrepreneur.
Hacker News doesn’t have search yet, however some smart folks have built a tidy search engine for the Hacker News community using the HN archives and Solr.
SearchYC.com is so good, that I use it first (shock! before Google) for start-up related searches. I got tired of typing the URL, so I wrote a FireFox Search plug-in for SearchYC.
In firefox, click this link to install.
