I was thinking about making a mastodon-twitter crossposter when I came across this.
Its much better and easier to use than anything I would've made.
Been using it for about a week and I'd say its been a success.

Mastodon instance for attendees of Refactor Camp, and members of various online/offline groups that have grown out of it. Related local groups with varying levels of activity exist in the Bay Area, New York, Chicago, and Austin.
