Can anyone explain Twitter to an old fogey like me? What is "trending"?

[Snowth MkII]

How do you use it? Do you have to be on it all day incase you miss some sort of nugget?

On twitter "Trending" means something is very popular and a lot of people are talking about it a lot. It can be anything, too.

Trending is the crap that's being spoken most about at any one moment or in any one day. The rest you can learn by reading the help section of the website.

Trending topics (or TT's) are just things that alot of people are talking about on Twitter at the moment.

talk a load of crap see if anyone reads it, i was on for about twenty minutes found it a load of crap and come off,

Avoid Twitter. Unless you really believe that other people want to hear the random thoughts that you see fit to "Tweet". Twitter is for twits. Tweeting is for twats.

trending means what is popular and everyone is talking about. It's a shame that Justin Bieber has to be a trending topic almost everyday.

twitter is a website which allows those without much to say,enough room to say it in.....

trending is what would have been known in the post-friends 90's as "watercooler "talk

you're missing nothing.
