URLminder lets you connect to Beeminder and set up a goal to beemind the number of words you publish at one or more publicly accessible URLs.
This is a great way to Beemind your novel for NaNoWriMo. Keep your novel on Dropbox or anywhere else that's publicly visible.
You can use this application as a basis for other Beeminder integrations, like Beeminding a Twitter feed, your blog's Atom feed, other structured data on the web, or anything else you can think of.
If you publish/fork an integration, tell us about it! We'll collect them in some sort of central place so other Beeminders can discover them and use them.
You can also get started on an integration easily by using the OmniAuth strategy for Beeminder.
