Designing a Notification system
Looking into how to create a notification system like facebook.  I have a few ideas on what to possible do, but my friend said something about Graphs being of use?  I am working in PHP, but plan to switch to Python eventually to make an more efficient system with faster response times and such.

I can't provide too many details, because I don't really know what I am looking for yet.  Any suggestions on how to make something that is fast and scalable would be awesome.  I don't mind doing research on data structures if I am given the info on which ones to look into.

Thanks :)
