Links Will not Interfere with the Character Limit on Twitter

When using Twitter currently service users must be limited to 140 characters to post a message on the site. When such a message contains a link, that number drops even more, depending on the size of the URL and a shortener was used. But this is a problem that should not happen, according to a post on the official blog service.
Sean Garrett, vice president of enterprise communications, warns that links sent by DMs (direct messages) has passed the internal system of shortening URLs to prevent malicious attacks and other scams. This same system will be used to shorten URLs in tweets also published on the site. However, unlike the shortener used to DMs that generates links starting with twt.tl, the new system will create links that start with t.co.

Garrett also says the tweet posted the link should not be explicitly shown, being replaced by a smaller version or the title. A URL like http://tecnoblog.net/20791/twitter-prepara-proprio-encurtador-de-url/, for example, will generate a link started with t.cobut that will be shown on the tweet as tecnoblog.net/ 20791 or the title used on the page.

There is no estimate of when the new system shortening URLs will be made available in the web version of Twitter, but Sean warns that developers already have an API to integrate the new function to its customers from today.

Upgrade to 21:02 | As some readers have pointed out, the current URL shorteners could leave hurt by this very service Twitter, however, according to the official account @TwitterAPI, links that are sent to the site already shortened will not be modified. A link migre.me for example, will not be shortened, and then be re-shortened again using t.co. They only receive a URL starting with t.co and continue redirecting as they were before. In this case, however, two separate redirections occur.

Update on 09/06 at 24:47 | An article in The NextWeb blog clarifies the new limits: the link will take 20 characters of each tweet, thereby lowering the limit from 140 to 120 characters for tweets that contain links. Even if the published URL is short, it will be stretched to use exactly 20 spaces. Thanks to reader Raph4 (@raph4) for the tip!
