After the HF25, there is no more incentive for running a curation trail (unless you want to abuse it for circle-jerking, etc) so I don't know how this will play out.
Actually if you have multiple accounts to curate and comment in the tribes with and then following those with your main account where you have your HP staked then that is a great use of curation trails I think, you can give higher votes with tribe tokens and still not depleting your HP voting power.
