You make some good points here!
Also, articles that contained images and were tagged photography would only contain the image with no accompanying text other than maybe the title.
You can kind of get this already by using Steepshot. It's not exactly as you imagined it, but if you want a photo album type of interface, then this is a good start.
Sub-tags is also a great idea; and very easy to make happen. As long as the community agree to use this it could be done without having to upgrade the Steemit UI or the Steem blockchain, since these are essentially just alternative tags.
The subtags idea is similar to my idea but not as complicated. :-)
Yeah, that's true, but the good thing about subtags is that they can be done without any changes to anything, so just decide on some of them, use them, and they're active :)
Of course, I really do want to changes to the tag system, either from the blockchain directly or from the Steemit UI. It's not working very nicely at the moment..
I'm not sure either case would require changes to the blockchain itself. I'm going to do a garbage post to see if machine tagging works on the blockchain or if it will break.
It seems to break. lol. This is okay though. I could just merge the ideas. #tag--subtag---value. This could still provide something easy for a script to parse. and its instantly usable as you say.
