This was an issue when Twitter/Facebook/Instagram switched from chronological feeds to "curated" feeds. i.e. Let's increase the echo chamber.

Great point.

Also, I think a problem is one person can only send one like.

Returning to my example, I'd like to be able to give the litter picker 20 likes, and maybe the Selfie uploader 1 like.

I think there has to the option of another accreditation technology which runs across social networks.

It's an area I'm interested in and looking to do my next project on...

Then you should go to slashdot, they have been doing that for awhile...

[smcnally]

Doing which? Allowing multiple likes? Cross-site accreditation?

Slashdot hands out Moderation points sometimes, and asks people to meta-moderate sometimes -- both different from Likes.

[slau]

For varying definitions of "sometimes."

I don't visit Slashdot anymore, but for the period between 2004-2010, I had virtually unlimited mod points.

[smcnally]

Understood. Even then, though, you couldn't mod the same item more than once, iirc
