Forcing us to tag at the end of the post creates potential redundancy. It would be nice to be able to say something like "I think #twitternotes is awesome." But the way you're parsing the hashtags is creating redundancy because I'd have to write "I think twitternotes is awesome #twitternotes". The first post would have the tag "twitternotes is awesome" while the second would have the tag "twitternotes". Please fix this. Contact the guys at
http://hashtags.org to use their regex if you need to on what exactly is a parsed as a hashtag and what is not.
