Listening to every heart
Erin, good of you to point out what is an aggravation to a lot of us! As has been pointed out, when you see someone posting, posting, posting and not a reply to be seen, allow that person's work to receive "The Passionate Plummet Award".
Then, as you have been doing yourself, which so many have pointed out, is to go ahead and reply to others. It never hurts to continue with a good example. If you are replying to someone who tends to post more than respond, then invite that person to view your work and welcome them to comment on it. Sometimes, believe it or not, some folks think they can only write, and are a little timid about offering comments and/or constructive words.
Thanks for bringing this topic to the right Forum, too!
