RSS feeds vs. widgets

Judging from our blog posts, setting up RSS feeds seems to be one of the more challenging explorations. I am wondering whether the library might want to think about offering widgets instead: programming widgets, readers' advisory widgets, etc. (Ok, I am still not exactly sure what a widget is, but I think my husband has one from NOAA sitting on his desktop that gives the forecast for our zip code.) An RSS feed that isn't particularly active might simply be purged from our users' computers, but a widget gives them control over when to click.
