i personally find no use for them.. although they give others a chance to get noticed, though theres a good side and bad.

The good first: income on their content, also a chance to attract others interest on similar topics.

The bad: unwarranted attention flagging due to numerous reasons to jealousy which we see on here often, lastly the percentage of still being ignored if resteemed...

It's a risk though the fees aren't too high at the moment.
