Facebook: "To avoid overwhelming users and servers, we only show the most popular posts, using an elaborate algorithm that incorporates likes, shares, and views. Oh, and being paid to show it helps, too."
Tumblr: "We fix that problem by limiting posts to 50 per day, per blog, and by encouraging queued postings. Oh, and blocks help too."
Twitter: "120 chrs @ a time. Plus users get used to Fail Whale. LOL!"
Google+: "l wish I had that problem."
MySpace: "What problem?"
Me: ...For a bunch of social networks, you are all pretty goddamn antisocial.
