Oh, if that's your concern: I'm not intending to become a witness. I'm just interested in the system and the economics behind it.

It wasn't a concern about you joining, it was the opposite - I would like to see more witnesses join (not less).

Also, I wasn't necessarily speaking of you specifically - anyone who can add value to the platform through a witness campaign would be good to consider it.

I would like to write a speculative post about witnesses, but I fear downvotes. Can you promise me to undo possible downvotes by zeroing them out with an upvote big enough?

Well, my upvote is not nearly enough to counter most of the the larger stakeholders. I also can't guarantee that without knowing what the content of your post is.

In general though, I would encourage people to post what they feel is important even if it means becoming targeted.
