Great post! I have changed my languaging around “lurking” I now call it “sampling”. I fully agree that there are many instances where because of time, interest, or lack of any strong opinion or expertise, I choose to sample. I am also in agreement that it is a pity if you are “always the bridesmaid and never the bride” i.e. you only sample and never contribute.
So much learning comes from watching what others model and I think it wise if newbies choose to sample until they feel comfortable and feel they have something to offer! I love @dogtrax post which reminds me of Milton’s last line in his poem, On His Blindness – They also serve who only stand and wait.
