I had to post something like this to help other readers get familiarized with certain applications and tools available online. Let’s start with Twitter.
This is basically a social networking service that sends text-based posts to update the user’s status and be displayed on a particular site or blog. People who have signed up to receive updates on a particular user are the only ones who can see these updates. Updates can be received instantly after the update is delivered via the service’s website, instant messaging, and even via SMS. Updates depend on the location of the user and receivers.
