Hello.

I'm looking for a few web services that don't seem to exist yet. First, a way to save my Twitter favorites to Instapaper (or similar services). Second, a webhook that sends content to Instapaper, as I dislike relying on third-party app integrations. Finally, a service that sends full RSS feed content directly to my email inbox in near real-time using pubsubhubbub. Existing services only send partial archives. If I can't find these, I might build them as open-source projects.

I'm considering adding an email subscription option for blog updates, as an alternative to RSS/ATOM feeds. Would you subscribe to email updates if offered?
