dopplr - Add trips by Twitter
You can add trips easily on Dopplr using a Twitter account.
There's a special Dopplr user on Twitter that is there only to receive messages from you, which then get turned into trips on Dopplr. You can send it a message by twittering something like "D dopplr a trip to Helsinki on May 19th until May 23rd", or you can also use the "@dopplr" prefix if you don't mind the details being seen in 'public' on twitter.
Start your message with "d dopplr" (to send it in private) or "@dopplr" (so it appears in your Twitter timeline). Make sure to mention a placename and two dates, including the month both times.
