Speaking only for myself, I wouldn't vote for such a rollout unless IB categorically refused to modify the software to allow per-forum enabling of reader feedback. I doubt I would vote for a sitewide rollout in any case, other than a limited duration trial so we could see just how bad the results are in OMNI/PR.
So, rather than ask them to work on improving mobile access, you'll ask them to modify software to allow per-forum enabling?
