Micro-blogging and specifically the service Twitter are quite a hype these days, which is not justified in my opinion. Let’s describe what Twitter allows you to do in one sentence. With Twitter you can write posts of no more than 140 characters in length which are displayed on the user’s profile page and sent to other Twitter users who wish to receive them or only the user’s friends.
So in fact it’s nothing more than ordinary blogging with a restriction that you can’t use more than 140 characters. There isn’t much difference with ordinary blogging, is it? I can start writing posts on my weblog which don’t exceed 140 characters, and everyone who wishes to read my posts can use the RSS feeds or visit my weblog. The only noticeable difference would be that posts on Twitter don’t allow comments, replies to other users’ posts constitute a post on their own. Twitter allows restricting posts to friends, but so does WordPress allow password protecting posts. Maybe the single advantage of Twitter is the feature to send and read posts via SMS messages, but for me personally this advantage is void because I never send SMS messages. I don’t want to spend money on sending SMS messages. I don’t know if SMS is a serious advantage for others?
So it’s nothing special, isn’t it? If you disagree, then at least read about Twitter’s policy regarding privacy, which could concern you. And Twitter is not an open system, it doesn’t work together with other micro-blogging services, Twitter locks their users in. So why not migrate to identi.ca or another open micro-blogging service?
