First introduced in 2009 by Twitter’s own Nick Kallen, Twitter Lists have become the most loved Twitter feature for many of its loyal users. And yet, Lists have barely been updated since then.

Twitter Lists have been the red-headed stepchild of Twitter. Relegated to sitting in the corner, eating paint chips, and forced to watch its siblings get a makeover after makeover.

Over the years, other companies have stepped in to leverage Twitter Lists in a way that Twitter wasn’t interested in doing. Most notably, Listorious (now defunct) was a popular directory of Twitter Lists. It had a rabid user base, and a strong mindshare in all things social.

Alas, Listorious has gone the way of dodo bird earlier this year. But not to worry, another plucky Internet startup has grabbed the reigns and is giving people what they want. A better ways to manage lists.

List.ly is all about lists.

You can make a list of people, places, links, media, even apps. Once the list is made, you can embed it (and allow others to do the same) in your blog. You can even allow others to manage your list with you. There is a voting feature, sharing, and bookmarking. In short, it’s collaboration at its finest.

And now, List.ly is rolling out a full integration with Twitter Lists.

Here’s how to supercharge your Lists

The first step is to have a Twitter list. It can be an existing list, or you can create a new one.Your Twitter Lists can be empty or populated.

The next step is to create a new List on Listly – a “Twitter List”. Next choose your Twitter list to map to.

Each Twitter list can only be mapped to a single Listly lists, so you won’t see a List that’s already been mapped to another list.

Once you have connected your list the members of your Twitter list will be imported to Listly.

You can also import the members of any other Twitter List by using the quick add option. Quick Add also lets you just type in a number of Twitter handles separated by spaces.

These will be imported into your list, intelligently excluding duplicates. Anything you add to your Listly list will be added to your Twitter Lists within 10 minutes.

You will receive a notification from Twitter when any batch processing is completed to tell you that your list is ready.

You can choose to turn list moderation on. That way the items added by others will be sent to your moderation queue.

When you move people from the queue to the list the will be added to Twitter. When you move people to the queue they will be deleted from Twitter.

You can share the whole list or an item on the list, which is great for focus.

It’s advisable to thank people for contributing. People can always see who added which people to Listly. The list can be filtered and sorted.

You can embed the list on your blog. There are multiple layouts to choose from.

Anyone can embed your list.

When you embed a Listly list it is in effect a people directory. That’s different that embedding a Twitter List, which only shows recent tweets.

The embedded list is responsive so can be placed in a post or a sidebar.

The content of the list is treated as a part of your post.

Your list will keep changing over time, which also means your blog post will keep changing too.

Items on the list are automatically coded with H2 tags, which helps search engines identify the most important information.

If you authorize Listly to connect via G+ and you add Listly as a site you contribute to on G+ you will see your authorship avatar in search results.

The final part of the process is to subscribe to your list. If it’s your list you don’t need to subscribe, but other people can.

Because your lists become more valuable to others as they know they can submit corrections and extensions to your list.

Twitter Lists alone only let you create OR consume. With Listly, people can contribute.

Once you own or subscribe to a list your can use your list to focus your time and attention on Twitter. Lists are usable from all the major Twitter client tools.

Go ahead and check out List.ly and make your Lists truly collaborative and social.
