The biggest Twitter users are adults.Most kids will continue to talk to their friends through instant messaging and texting.
If your kids are Twittering, they only have 140 characters to say something -- and they have to say it to someone who has already asked to “follow” them (this isn’t as creepy as it sounds!)
Anyone can Twitter -- there's no age restriction --- and those who do have to set up a personal profile, which can be public or private.
Twitter helps people communicate and stay connected through the exchange of quick, frequent, 140-character messages. Choose whose messages you want to receive and how you want to receive them, or search all Twitter updates to see what people are talking about.
What is following?
Following someone on Twitter means getting their updates in your personal timeline. If you follow "Tina," for instance, you'll get her updates on your homepage when you log in -- or on your cell phone if you've added it to your account. You can see who gets your updates on your Followers page -- and make changes to who you follow on your Following page.
Do you follow me? (What are followers?)
Followers are people who receive other people's Twitter updates. When you post an update to your Twitter account, your followers will get it on their home page and/or phone. You don't have to follow everyone who follows you, and unless an account is private, you can follow and un-follow whoever you want without them following back. Mutual followers can send each other private messages, and you can even choose to get notified by email when someone new follows you or sends you a private message. Your follower/following stats are listed on your profile page.
Can I restrict who follows me or sees my updates?
Yes, by protecting your profile -- which means that everyone who wants to follow you must submit a request for your approval. Only approved followers can see your Twitter updates, which won't appear in search engines.
Once I start following someone, can I stop?
Yes. Visit the profile page of the person you want to stop following, click the "following" button to expose the drop-down box, and click "remove." Twitter doesn't notify you when someone has stopped following you.
I don't want a particular person to get my updates, but I don't want to protect my profile. Is that possible?
When all else fails, you can block someone. Look for the block link at the bottom of the profile page under the friends icons.
