Ureka.org is the social network I run that has recently been converted to run the Steem blockchain. The integration is partway complete and works - with more features coming soon. I have just added Ureka to the awesome site 'AlternativeTo' that lets us find alternatives to software products and apps that we already know - so, for example, if you want alternatives to Twitter you just search for Twitter and up pop some alternatives you could try.
I would really appreciate if you would take 1 minutes to sign in to AlternativeTo (just use a login for an existing social site to do so) and give ureka a like and maybe a review/comment if you already have something to share: https://alternativeto.net/software/ureka-earth-heart-community/
If you let me know in the comments on Steem that you have dropped a like, I'll upvote your comment to say thanks. <3
Wishing you well,
Ura Soul
