We should make users aware that they should choose the first tag based on the content. Will that work?

Very hard to say - we've discussed a lot in the past about using appropriate tags and I think that even steemcurator has mentioned it. Unfortunately, most people still just use generic spam tags.

Maybe option 4 would be to leave it out, I just mean url with username and permlink only. The main thing is to get rid of hive-xxx, that seems to me to be the most important thing.

I don't think there's any penalty for having the hive-xxxxxx, we're just not benefitting by having something more meaningful. So removing it would probably have the equivalent effect to doing nothing (although I don't know this for sure) - and it'd be a mission to unravel Condenser's Routing.

I think the only way that the existing might be penalising us is that the URL should generally reflect the content on the page. So a URL that contains "/football" when the body content has no mention of football, would treat the page as "Tag Spamming" (the "official" term for this eludes me). For options 2 and 3, the community name already appears in the page ... and if bad tags are chosen, then option 3 could potentially have a detimental effect.

Thanks for sharing your thoughts. New thoughts tend to surface during these discussions.
