This final note today, in which I've never been so happy to see Promoted Tweets.

That is, tweets that companies -- or, in this case, a person -- buys special placement for to get 'em extra attention. Ads, basically.

Anyway, a British Airways passenger who tweets under the handle @HVSVN got sick-and-tired of the airline not returning his emails about his lost luggage. He took to Twitter to vent -- but not just his 500 followers.

He bought a series of promoted tweets to target all of British Airways' 302,000 followers to spread his message.
