Yes it's silly and annoying.

Tumblr has very much the same program regarding reshares. Although I'm not sure if Tumblr even wants to foster discussion on their site--people do it any way, of course, quoting each other, but most Tumblr themes make these kind of discussions look awkward and hard to follow. Nested quotes get thinner and thinner, until you have just one word per line, sticking halfway out the container.
