souunds like a great idea, some tome ago I was talking to @oixiepost about a #fiveonhive thinking that the concept is a great one, just didn't quite know where to place the 5 :)
The sharing of community members and their posts is a great concept and especially posts that feed or inspire other posts and generate lots of community activity.
@slackerman has started a challenge over at the CTPTalk swarm where people list 5 posts of others, I believe it to have great potential with some tweaking.
Any project that promotes others and ultimately increases community engagement on HIVE is worthwhile, after all it is the engagement that makes HIVE what it is
Hive5 Challenge is focuses on increasing our presence on Twitter. At the moment I want to keep it very very simple then move forward one day at a time.
I'll certainly reach out to @slackerman very soon :)
