Since Twitter has been officially crowned the latest thing we can't live without that we never knew we needed -- in the grand tradition of other such recent items as Facebook and the iPhone - I'd like to propose a number of Twitter spin-offs that I think could possibly have legs. This also follows another grand tradition; that of taking something that's hot and spinning it off into dozens of alt platforms. (see: iGoogle, iChat, iMovie, iPod, iTunes, etc.)
Bitter - nothing but gripes and complaints - but only if they hang on and make you crazy
Critter - where denizens of sites like Catster and Dogster can post tweets from their pets
Fitter - gym-rats only
Fritter - recipes for waffles and pancakes et al
Glitter - for queens in full regalia
Hitter - for baseball fans
Litter - tweets about litterbugs, both corporate and individuals, in real time
Knitter - a moving billboard for those who like to knit and purl
Quitter - if you've left your job recently this is for you
Shitter - for tweets posted while sitting on the can
Tater - anything relating to the potato, a very versatile vegetable
Titter - dual purpose; a constant stream of one liners and tweets about breasts
Tooter - a feed that relates to the release of intestinal gas
Traitor - for the Benedict Arnolds out there
Tutor - strictly for teachers
Twatter - a real time feed for prostitutes and their customers
Zitter - for dermatologists only
- and -
Teeter-totter - for the under-five set
