when i found out about BlogRovR, i liked the idea. in the 2007 spring semester course on
Web-based Publishing we were trying to build the exact same thing (our idea was to use the Technorati API for finding blog posts about a page). furthermore, the general idea of browser plug-ins for getting additional context for a web page is something i find a useful idea in general.
BlogRovR has a firefox add-on that produces some configurable pop-up whenever somebody has blogged about the page you are currently viewing. but the pop-up can get pretty annoying, so it is essential that i can switch off something like that when i know i am doing something where i don't need and want it.
but as it turns out, even though you can switch off the add-on, it magically switches itself on pretty frequently. i did not completely figure out the rules (whether it is just time-based or something else), but this kind of obnoxious behavior definitely deserves an immediate and complete uninstall. i never liked the stupid dog theme anyway...
