I am a self-confessed stickler for correct syntax, grammar and orthography.
I'm also an atheist.
Note the spelling.
So, as part of a testbed project in twitter programming, I've built a little software robot called @AthiestBot which will remonstrate with users that mis-spell "atheist" in the most common and annoying manner.
The bot is slightly more sophisticated than some bots out there, and I plan on making it more sophisticated still. For one thing, it won't tell you off twice in rapid succession, though it may respond to you once a week. It will also attempt to figure out if you're trolling, or if you should know...
