This article is a few years old, but I think it hits the nail on the head. The general craptacularity of many parish websites really makes the church look sort of pathetic and uncool in the very attempt to look otherwise (ala the use of sappy guitar music at Mass). This is something friends and I have been amused by before. Even some diocesan websites aren't that great (it seems only archdiocesan status guarantees a reasonably professional-looking website. Reasonably so. Though usually, like the Vatican's website itself, still not stunning). Get with it, people!
I especially like:
-"Turn off the music, eliminate any cheesy animated gifs and flashing text, remove any visible visitor counters and get rid of (what you might think are) really cool animated menu thingies."
-"For St. Pete’s sake, remove the upcoming event info inviting everyone to come to the Fall festival…that happened last year."
