I have a script that gets a bunch of data and emails it to me and some co-workers every day at 7AM. Stuff includes: high temperature/probability of precipitation for the day, bitcoin price, iTunes/Google play sales/rating values, number of "diff" lines in web pages, number of followers on Facebook/Twitter/Google+. The latter isn't entirely a vanity thing... some co-workers manage multiple social media accounts and it's nice to know if readership is going up or down.

Part of the point was a) to aggregate everything in one report to reduce the temptation of looking at something multiple times per day, b) to avoid visiting multiple pages in order to find all the information, and c) to find changes in things that I may have forgotten about since they rarely change.

I've thought about making it available for others, but it'd take a bunch of work, and I'm not sure what the demand would be like.
