Power users will always exist. Hell, there are power users in real life.

Doesn't mean the scale should be tipped towards them. Necessary evils should be minimized, not accepted as basis.

| But here on hubski, your status as a "power user" doesn't affect me.|

Au contraire. Suppose I posted nothing but cat pics. I would soon attract a following that loved cat pics. New visitors to Hubski would see a predominance of cat pics because I, as an influencer, create an environment favorable to cat pics.

You're secure in your selection of followed individuals, but are they? Are the people they follow? As the general content starts sweeping more and more towards cat pics, it starts becoming an environment that is friendliest towards cat pics. Those who wish to view something other than cat pics are discouraged by the paucity of decent content compared to cat pics. Before too long, the people you're following aren't posting any more. Me and my cat pics, on the other hand, have gone off and formed the SFWCat network.

Some people will follow #catpics. Let them. Some people will block #catpics. Let them. There's no logical argument for allowing the existence of tags but only making them viable for blocking. Meanwhile, you lose exactly nothing by having tags be a viable way to discover content - you don't have to follow any, just like I don't have to follow any users.

So tags are, at best, useless because you're already following the good posters, and at worst, will clog your feed with bad content.

I'm following like four people right now, and that's new. Tags and global are pretty much the only way I'm getting content.
