Some of the categories that I could think of are as follows:-<p>1) Automate X task.
2) Curated list of X delivered to Inbox.
3) Simple API for doing X.
4) Integrate X with Y.<p>Would love to hear the thoughts of HN community on this.
Here's what I pay for:<p><a href="http://nsscreencast.com/episodes" rel="nofollow">http://nsscreencast.com/episodes</a> $9/month.<p>Github is $12/month.<p>Ask people what they actually pay for because people might not spend the money once you build it.
