I didn't know someone suggested you check out my posts, that's nice. I also think it's good that you've been motivated/inspired to be a little more active and interested in people's posts than you would have otherwise because if the weekend-engagement. That's what it's for.
You make some good points and yeah, so many get no comments...I see that too but a lot of times I check their accounts and I see that they make no comments to others so usually they have themselves to blame. It's a two way street.
With your vote...use it now matter the monetary value of it as it's just an endorsement, positive reinforcement, on the post you leave it on. It has value of a different nature.
Thanks for commenting.
