Webmasters currently face link rot as a major website maintenance problem. As we rely more on Google and other third parties for features such as hosting, ads, and content syndication what happens when some of the business relationships that are opening up content fall away or search engines reorganize and rebrand their offerings?

A few weeks back I made a post about the book being a dying format, and in that post I have a Google book snippet. Within a week that snippet was broken. I had a Google CPA ad integrated into one of my major websites and the ad went away, breaking 10% of a large site and making it look like spam.

Even some of the services that are not broke will likely be drastically different in a few years. Google maps is really open because they need marketshare, but after they become the clear market leader will they stay fairly open? How long until we have ads in everything?

A good webmaster service that would be exceptionally useful is something that scours websites and looks for broken stuff. Think a Xenu Link Sleuth for multimedia. Another would be how to guides on how we can enable interactivity without becoming too reliant on any third parties that break our sites.
