Interesting article. Quite honestly, the sharing of the peace is one thing I look forward to. We are a small church so it is much easier to do, but we get out of our seats and go around the whole sanctuary making sure to greet visitors. Almost like a chinese fire drill at times. :-) The main reason is because there is nothing worse than being new and no one greets you during this time. We have been in that position many times and it is just awkward. I tend to not greet the long time members who just stand there waiting for someone to come and spend the time reaching out to visitors instead.
So I would say that if you can’t “do it big” dont do it at all.
