I must say I sort of agree, I started using my #justbecause tag as the first tag on most of my post because no one could tell me to remove it for tag abuse. I don't know if they fixed the first tag changeable or not, but not taking chances with it.
I sometimes remember to throw a Tribal Tag in every now and then, but not often any more. I am trying to move back to having tag fun. Prior to the tribes my tags looked something like this:
justbecause alaska hasmoose moosemonday animatedgif.
I use to like to have fun with my tags, now they look something like justbecause palnet steemleo virtualcoins neoxian.
The tags fit with the communities, but other than virtualcoins give no clue as to what the post was about, (nothing other than my first dozen coins/tokens, I got).
I look on all my Tribe feeds, and they have some nicely chosen categories, especially the Sports Talk tribe, but with all the Tribal tags being used, are any of the category tags being used. If we have to just scroll down through the primary tag on a feed it did nothing to help the content consumer like me. I may as well stick with surfing the trending tag on steemit.
I am trying to return to tag fun, if I can ever get around to creating a post again. Learning takes a lot of time.
Pretty sure first tag remains unchangeable and becomes the 'category' choice.
I used to play with my tags too, knowing that they were never used so much to locate content, but nowadays it is tempting to go for the default content tags - particularly as I have stake in all of them.
I like what sports have done with their sub-tags, although had nothing to offer there today, I can usually find one. At present though, I can go through the 'New' link on most tribes - neoxian and marlians are a bit an effort though.
