Twitter Tools
Twitter offers some tools to aid with the Twitter experience, the most important of which is their Analytics suite.
Twitter offers a comprehesive analytics suite, which allows one to keep track of statistics on a given account. This enables users to make changes to their settings and behaviour to improve the Twitter experience.
This is a powerful way of using Twitter, allowing for a number of columns of information, to be customised by the user. Columns can contain notifications, user posts, trends, Direct messages, etc. It also can handle multiple accounts, at once, each in its own column.
To use TweetDeck, just navigate, in your browser, to https://tweetdeck.twitter.com/
For Windows users, there is an app, called TwitDuck, which does exactly the same thing.
