I thought it was awesome until I read "publically" on their site, and then clicked away. If they can overlook a spelling mistake on their website, how can they be trusted to archive PUBLICLY available tweet since 2006?
"Publicly is certainly the commoner version, but publically is a logical alternative, mentioned in the OED with half a dozen citations from 1727 to 1998, so it can't really be called a mistake."
