Twitdom has the potential to be the best directory of Twitter apps (applications) or Twitter tools in the near future.
Many consider Twitter Fan Wiki Apps as the best directory of Twitter apps or Twitter tools but that will soon change now that we have Twitdom (currently in beta), the first database dedicated to index existing and new Twitter apps or Twitter tools.
So far I can see that Twitdom has some nice Twitter tool/Twitter app categories; Browser Plugins, Desktop, Mashups, Mobile and of course Web. Just like Twitter Fan Wiki Apps, visitors and developers can also submit new Twitter apps/Twitter tools to Twitdom and no registration is required. Just fill up the form and hit submit. Go ahead and submit a few if you have them. Take note that Twitdom only has 63+ Twitter apps/Twitter tools as of time of writing.
Twitdom is not yet recognized as the best directory of Twitter apps (applications) or Twitter tools but it will one day (unless we have something better in the coming months). I will revisit this post every now and then to keep you folks updated. :)
