I guess to a lot of people and users it's not useful, its all just tweets like "i just cleaned my cat, he's hair is sticking up! yeeahh, freaky" or "i just had cereal, the milk is too warm"
It's how you use it. I follow people that I like in the art community and find give useful commentary and link to useful sites. I also follow people who's comments are relevant to the web design and other various programming communities.
I have done some networking through it and it really forces you to get to the point. You only have so many characters. No mumbling or pansy crap. Just get things done.
It's really streamlined a lot of things.
A lot of comedians are on it and they post lots of jokes. It's hillarious to follow them.
So while yes, a lot if not most of the time its just spamish stuff or useless, if you use it right, follow the right people and acquire the right followers than you can make something out of it. But if you just ignore it, then it's not going to do anything for you.
I use Twitter often. It really allows me to communicate with people easier. For some reason people are more keen on answering questions on Twitter than on email. More often than not, I'll never get a response by email.
It's entirely how you use it. I mainly use it to get news updates and follow news personalities I like, as well as artists, plus have made a handful of regular correspondence through it. I've seen some use it entirely for friends, others as a giant loud speaker, so just try it out and see what you find. Sometimes fans just like seeing the actual like, plus latest works, of artists, such as yourself.
It's usefull when we know how to use it. Very different from FB, not the same. You follow what you find interesting, people you like ( it could be ThePixar blog or NYtimes, you have the choice. )
It's a complement of newspaper.
DO NOT compare with FB
It all depend on HOW you use it. I personaly don't wtweet very much, don't have alot of flowers. vit i'm flowing a lot of people that make me knowing all what i wanna know about what is happening today in the world.
Useful or Useless? It's a personal question! The majority of people here find that it's not something usefull, but i'm not that opinion. It all depend on HOW you use it.
Don't hesitate tu break the glass and after searching people / things you like! With time, your timeline grow up.
Depends on the purpose. If you want to update people about something, then it could be good; for example the progress about some art or maybe some news about a movie and so. Use it like a chat or so...no way, its not the right tool in this case.
And the worst thing is when people get tweet-drugged and cant stay without it...same going on facebook...and those people become like zombie...
Like any other website, twitter is all in How you use it, and what you make it do for you. I've made business contacts through it, found jobs, made friends, made contacts who can assist me in furthering my photography goals, and I use it to follow notable people and for the odd contest to win a camera.
I always tell people, If you're not sure if it'll be helpful to you or not, Its Free! Try it and find out. Worst case you waste a little time, best case you it helps you achieve goals. To me that possibility is worth the time either way.
