I had seen a few posts about the list.ly service, but this post from social media examiner offers a really cool use for it that invites community participation. list posts are the evergreens of the blog world - what are some other ways you could see a crowdsourced list like this being a good thing?
Create a Community-Driven List Post
List.ly is a collaborative list-building tool. You create the initial list on the List.ly website and you can embed it as part of your blog post. Embedding means that it appears as if it’s in your blog post, but it still resides on List.ly.
What’s cool is that your community can then add and/or vote for items on the list. This can be a useful tool to engage with your community and discover more about their interests.
