Just in case the chrome fish adhered to the back of your car isn't enough to remind you and your friends of your religious affiliation, there's a Firefox Add-on called Bible Fox to change your Firefox toolbar into a gallery of religious symbolism.

Common Craft has tackled yet another [InsertNoun]2.0 topic in "Plain English." This time it's social bookmarking.
Chances are pretty good you already use some kind of bookmarking system, whether crude or sophisticated. Bookmarks are just handy things.
I switched from saving bookmarks in my browser (Internet Explorer calls them "Favorites") to online bookmarking tools a couple years ago - except for a couple key links I use everyday. This is primarily because of the portability of online bookmarks and that they are easily shared.
Social bookmarks take the advantages of online bookmarks and build in the collective interests of others like yourself to help you discover that which you might have missed otherwise. I could explain further, but the video does a pretty good job.
How you could use these is pretty endless. You could share your collection with colleagues and your congregation or just enjoy the benefits of gathering good sites through the recommendations of others with similar interests and needs as yourself. It all gets back to better ministry with less effort and expense.
