On twitter, those words with # before them are called hashtags. They mark tweets from a certain group or for a certain effort.
For example:
#tweetsgiving was for tweets to help a thanksgiving charity effort
Some of the top hashtags in use on Twitter these days are:
- #gno same thing for Tues nights' 9pm Girls Night Out chat
- #journchat is when people are tweeting as part of the journchat weekly discussion
- #tcot top convervatives on twitter
- #followfriday who you'd suggest people follow, all day every Friday
- And of course, whatever conference is going on at the time, they usually have a hashtag for people who are tweeting from it
