Lest you think I am just full of smoke, mirrors and hot air, here is suggestion number two.
There are, at my last check 20,784 tags created on the Steem blockchain.
Many are likely errors and mistakes.
Many more belong to the dim, Dark World of NSFW.
And likely many are actual communities of people using one or more of these tags to post and perhaps communicate. For example 'poverty', I believe, does not show up on the main tag lists of any platform, but has attracted 285 posts at last check.
Using Asksteem it would be possible to check for communities out there with active posters, and add those links to this site (chainBB) as you wish, especially for your existing customers. Then send a post/ message to them announcing the addition of their tag to the chainBB Forum.
Really great idea?
Glad you liked it @jesta
