Yeah, but how about participating in one of the curation guilds? Pick the one that votes for the type of content that you like. That way the cost is zero, you provide value, you get some returns.
Also, for a lot of people those $0.20 could make a lot of difference. Oh, and there is the thing that those $0.20 are actually a lot in SP tokens, especially if (or rather when) the price goes up.
