That's simple because, there isn't enough quality posts been created. You don't expect meriters to hand out merits to undeserving posts (in their opinion) just because we want more merits in circulation.
That is exactly what theymos wants Merit sources to do:
Speaking directly about those that have spendable sMerit. Merit sources have an obligation to spend their smerits allocated to them that's why theymos gave that suggestion but the average users doesn't have that obligation. People are always too quick to complain about lack of merit circulation forgetting about the possible cause of that which is lack of quality contributions to award the merits to. No doubt much merit aren't circulating around but if we were that low on circulation of merit I'm sure theymos won't have hesitated in appointing new sources from the numerous of applications we have on meta (including mine).
@fillippone what burns lol. Its been long we encountered each other. I always link a thread relating to my thread or any other source when I see the need for one. If it does help numerous forum members, I don't see an issue with that.
I've been closely following your posts for some months now and I just have to say that they are definitely above par,and I admire the way you construct your posts always with links to make things clearer and easily understandable for readers.
Hardwork sure pays off and you're testament to that,congratulations mate!, keep it up
