@Felthry
1. someone on Twitter suggested something like it in, like, 2007 - https://twitter.com/chrismessina/status/223115412 - in a tweet that doesn't explain specific reasoning
1a. my best guess is "sending tweets via text was pretty standard at the start of Twitter and # is easily accessible even on a non-smart phone"
2. my best guess is "sending tweets via text was pretty standard at the start of Twitter and 160 characters of text message doesn't leave much room for separating metadata from text in 140-character tweets"
3. agreed they should be separate
@Felthry yeah, it's a kludge and not a good one
