I don't think so.
No, Twitter is a free service.
Unless you have a mobile phone plan that supports Twitter, then yes, Twitter will charge you money.
No. There is no charge at all Twitter is free
As long as people want to use it.
It will eventually start to use advertising.
For going against the terms of use and most commonly, spamming.
The website Twitter does not charge anything for you to use Twitter from your cell phone. However, your cell phone provider may. You could get charged for sending or receiving text messages, or using the web from your phone.
Joining Twitter is free. As for mobile charges, it depends on your provider and your mobile plan. You should contact your provider to find out what you are and aren't charged for.
No a Twitter account is free just like Facebook and MySpace
Yes. Twitter requires Internet access on your phone, therefore, it has nothing to do with your text limit. It depends if you have a plan that allows you to access Twitter for free. No it doesnt . if you're gonna send your tweets to 40404 , it dont requires internet access .
Twitter does not use apps or games like Facebook does, so unfortunately you can NOT use Farmville on Twitter.
Anyone can use it..... unless the twitter is not blocked in your country.
