I like the idea of having a community on Steem but I'm not 100% sure if I am a good community manager/admin type person. It takes a lot of work to do it right. It's something I will have to consider.

I expect there will be lots of SMT's with no value.

If I look at Ethereum. According to the stats I found there are over 200,000 (two hundred thousand) ERC-20 tokens there. Loads of those have no value.
