I realised recently that Twitter can be under-used, with some aspects or tools overlooked. For example, upon reading an article (How to: Use Twitter lists) recently I realised that I do not use lists as often as I should.
Twitter lists allow you to group people or organisations into modifiable lists, letting you group people/organisations by categories or names. As the article states:
In other words, you can create a list that groups together people for whatever reason (the members of your family, for example), and then you can get a snapshot of the things those users are saying by viewing that list’s page, which includes a complete tweet stream for everyone on the list. Lists allow you to organize the people you’re following into groups, and they even allow you to include people you’re not following.
Listorious – Listorious is a third-party site that maintains a categorized directory of Twitter lists. You can search or browse through lists by category, and find the most popular lists.
TweetMeme Lists – Readers of Mashable will be familiar with TweetMeme, which exposes the most tweeted links on Twitter and powers the “retweet” buttons on all of our articles. Just like it does for links, TweetMeme also finds the most tweeted about Twitter Lists.
