My roommate explained it like this: Twitter is very similar to the “status” feature that I am constantly updating on Facebook and Myspace. A “tweet”, which is a short blurb of text that is 140 characters or less, lets people know what you are up to. It’s very much an “on-the-go” way to stay connected. Those with very little time and unlimited internet access via iPhones or other devices can update themselves on their friends’ and colleagues’ tweets quickly and easily using programs such as Twitterrific. Subscriptions through SMS, RSS, instant messages or email make the process that much faster. Even my beloved Facebook allows you to view tweets through applications on their site.
As far as posting your own tweets, that process is just as simple as viewing someone else’s. You can go through Twitter’s website, instant messaging, email, SMS or another third party application to update your profile. Twitter applications such as Twitter Blocks and Twitter Search add to the “at-a-glance” appeal of the site. According to Twitter’s company profile on Crunchbase.com, these applications allow users to search tweet conversations and see updates in a visual form.
Twitter’s potential in the PR field is immense. Presidential candidates are using Twitter as a publicity tool to keep the world updated on their status at the polls. Universities are using it to get various messages out to their students. Professionals keep in touch

Twitter’s possibilities are endless, and the convenience and simplicity gives this “micro-blogging” site an appeal that will ultimately lead to its mainstream success.
