As suggested they could be used as curation rewards from a team. Another idea is to use them to buy upvotes, but that needs to be established. Like e.g. rando or booster one could send pockets to e.g. 'pocketwhale' to get upvote.
Probably not many users use then right now. I sent all my pocket tokens to bitshares. So I distributed some to ppl on bitshares. Was not sure how to use them here. Now I need to send some back ;-)
Nevertheless I'll try to resteem pocket related posts to get them more visibility
Thanks J
A "pocketwhale" voting bot would be pretty easy to code up.
And it has been done @pocket-x
