Probably not good given their measly merit/post ratio (for example, Altcoin Discussion board had only 0.05 merits/post last month).
Even if there is a merit source there, I still wouldn't expect impressive results when you consider how many posts that board generates and how much of that is complete nonsense. If that person had 100 merits to allocate, they would probably still suffer finding enough good posts in any given month.
