So far we have three potential solutions.

I like your solution because everyone can include it on any or certain posts they publish. But it has the drawbacks of the collector post and the little upvote button, separate from the interface upvote button, which can be confusing.

The other solutions I know of:

• Activating the commend reward pool at a tribe level. Tribe management handles it, which is less flexible but also avoids complications for authors. The drawback is the inflation is unavoidably split between the main reward pool and the comment reward pool.

• Comment Coin - still in initial phases I believe, but should work by including the "CC" tag to your post. Rewards would be in this coin, so a general value, regardless of tribe or community. But author has the flexibility whether to include the tag or not.
