yank twitter links into delicious
#!/usr/bin/env ruby
# = Delighter - pull your twitter links into delicious.
#
# Takes the first link and submits it to delicious. The description
# will be the text up to the beginning of the link, the tags whatever
# hashtags are on the tweet. Let me know if you improve on this, it was
# pretty q&d.
