Why is that most myLot member post but never reply ?

There may be several reasons for this. First, if a person gets a lot of replies to a discussion, it may take awhile to catch up with replying to the responses. I've taken several days to catch up with some of mine. If someone starts a lot of discussions, etc., they may lose track of which ones they have and have not responded to. Second. Responding to a posted reply does not count on your count total (the one in the parentheses), so some people may not want to take the time to do it. I don't know if it affects the pay or not. Third. Some people are just interested in seeing how many discussions they can start and how many replies they can get, so they don't take the time to respond to posts. Fourth. Some people are just thoughtless and don't realize it is the polite thing to do. Not everybody is ok with the lack of response. I'm not and I try to reply to everyone who posted on my discussions. Do what feels right to you.

Good Discussions topic dude :) i wanted to know it tooo neways wat i think on this question is tht many r lazy to reply to the topic wich they dont feel like to as it may also depends on several issues as said above in the 1st responses (+++) credited to thos question peace :)
