Those repeated alerts are making me a bit crazy. Also sending me Home Page urls instead of Permalinks. By the time I check, the home page has often moved on.
I guess it's just a minor annoyance to put up with, and the trade off is seeing more deep mentions, more social media and such. There are new services popping up all the time now that promise they "deep index" social media and the like. I imagine Google feels some pressure to keep pace.
