In my dream shul, there would be lots of interesting people to talk to the whole davening. There would be no uptight yekkes (redundant?) shushing everyone because they are having trouble focusing – after all, if they’re focus was so intense, they wouldn’t notice the chatting. In fact, they already don’t notice that nobody likes them.
There would be a rollicking kiddush after davening on shabbos where people who like to drink would drink, and people who like to eat would eat, and it would be paid for by the $5 fines that would be issued when people shush ($10 when they shush a crying baby).
There would be lots of seats in the shul and at kiddush. Every speech would be voluntary, i.e. not in the middle of davening (and they would thus be sparsely attended, unless the speaker took pains to make them really interesting).
And on behalf of my son, they would do Moshe Emes between each aliyah on shabbos and also on Monday and Thursday.
