That's an analogy used pretty often here, you're spot on! And it s true that there have been less friendly reactions to the reddit influxes before because of how the site mechanics worked. There has been some tweeks and now people can chose to ignore the newskis for 48h until everything settles down to normal and participate in the usual content instead. I actually like the influxes, explaining the site and welcoming new users but i can see how some people might find it disruptive.
Everybody that came over seem really cool, welcome :)
