BETA TAGBOARD is a Pinterest-like curation tool for #hashtagged social media posts. The simple search engine looks for a given hashtag across six major platforms -- Twitter, Facebook, Instagram, App.net, Vine, and Google+ -- and optionally allows users to pull individual posts onto their own 'tagboard'. It's not terribly different from favoriting a tweet, only you get to pick and choose from a larger and more diverse collection of social networks. Check out this #edtech tagboard to gauge whether or not Tagboard can help round out your PLN.
