Read Raptor — iMessage-style read-receipts & digests
Late last week I put together a quick homepage for an Assembly product called Read Raptor. In short, it allows you to integrate iMessage-style read receipts into your own applications, with the added benefit of digests that roll-up content that users haven't seen and delivering it at your discretion.
Like all Assembly products, Read Raptor is a mutual product, built and owned by the people who use it, and we encourage anybody to get involved and become a partner.
Check Read Raptor out at http://readraptor.com, or check out the product on Assembly http://assemblymade.com/readraptor
Anyone can get involved with an Assembly product. If you think you can help out in any way, check out Read Raptor's open tasks here. Completing tasks earns you a cut of the monthly revenue, so there's an incentive for people to contribute, moving the product ever-forward.
