I see it as a cool avenue for content discovery. I see it as a cool way to see which aspects of my Hubski contributions are the most appreciated. I thought it was pretty cool to go in my profile and see all the tags I've used. Think I need to rekindle a few of the old ones. I like the idea of greater customization potential
Cool, I'm glad. but I'm a little worried about echo chamber effect
If I never hear the phrase "echo chamber" again, I'll be okay with that :) -I don't see this as a way for me to be able to follow people that post things I agree with only and to filter out those that don't. This is not how I use the follow/filter for users, why would I use it that way for tags? I do see this as a way to protect the integrity of tags I enjoy. I see it as a way to follow aspects of people that I currently do not follow and get more granular with things. I don't follow mk, I don't follow bitcoin because I'm not that interested in most of the content there. But I have found that I enjoy the bitcoin posts that mk makes. Therefore, I'm now following #bitcoin.mk. There are any number of scenarios that could present this way. If I'm being filtered out of my favorite tags, and it starts to feel like I'm just shooting submissions into the void, doesn't that create a disincentive to post anything at all?
Knowing the content that you've posted in the past I find it hard to believe this would occur to you. That said, there are some users that may have their askhubski.user posts filtered. I can think of a few people that I currently follow that I would do this to.
