If you do spend time to specifically award good posts, it could also be an option to apply for the merit source position, although you're only Full Member and that could be in some eyes an obstacle.
I always have many quality posts to merit, some people even make good posts while they correct me but at times do not have smerits to give, and I will not have option than to not give as I do not have at the moment. I wished to have applied for merit source when I 1000 merits but there were many people that have applied and yet not given, to the extent I noticed TheBeardedBaby wrote 'When Merit Source?' as his personal text as it has been so long ago he applied.
People that feels the same way that think they are good poster could have just applied for merit source, but it has been very long since merit source were choossn last, and there are some merit source that are no more active. I think the best alternative you is effective but might not be satisfactory enough is to report the post.
