Twitter lists are one of the most powerful features of Twitter, enabling users to slice and dice the thousands of people they follow into digestible mini-directories.

You can create your own lists – either public or private – or capitalize on other tweeps’ listwork and follow a list they’ve made. Twitter lists are under-utilized in general, but specifically so in terms of finding and following others’ well-curated lists that could save you time in your Twitter reading and help you form new contacts and leads.

And now, thanks to Twitter amping up each user’s capacity to support up to 1,000 lists with a maximum of 5,000 accounts in each, the possibilities are endless.
