Twitblogs allows you turn Twitter into a proper blog, giving you the opportunity to post more than 140 characters, add pictures and videos.
Twitter is a micro-blogging platform and theoretically you won’t be able to do much at Twitter other than post texts (tweets) and/or outgoing links in not more than 140 characters at one go.
If you wish to turn Twitter into some kind of a proper blog, you can use a new third-party application known as Twitblogs. Twitblogs allows you to post stories or say anything that requires more than 140 characters. Twitblogs also allows you to post photos and videos too!
Take note that you can use Twitblogs on your mobile phones and so far Twitblogs have been successfully tested on BlackBerry, iPhone and N95 phones. Twitblogs said that their third-party Twitter app works best on the iPhone though.
