At first, I used to try to always have at least 5-10 merit to share just in case I stumble upon some really good posts, but later on I gave up on that so now I just spend as I get them so now I generally don't have merits to share for more than a day or two. Just see no reason to keep them.

I used to bookmark good posts too and merited them after I got some, but also kinda stopped with that practice as it's pretty easy to find merit worthy posts if you are active enough.
