What was the essence of blogging in the early days? Publish small messages for your friends and family; write about what you were doing. Blogging turned out to a more professional form of publishing; people took it more seriously and started thinking twice before publishing articles — as I do.

Twitter is about micro-blogging. Fast publishing of small posts about what you are doing and share it with your friends and everybody. I heard about Twitter 6 month ago but I didn’t get it until it became very popular this month. Like all social networks, things gets interesting when a lot of people — and famous bloggers — use it.

The principle is very simple. Twitter limits your message to the length of one SMS — 140 characters** — so that posts remains short. You can post a message from your mobile phone, from the web or from pretty little apps to your personal Twitter page. It’s actually a mix between blogging, RSS new feeds, instant messaging, SMS and IRC.

It’s funny how things turns in round though.
