Compared with Google+, Facebook feels old, stale and bogged down
by problems and limitations. Just a few examples: Facebook’s
EdgeRank censors most of your posts secretly, without telling you;
most of your friends never see what you post. Longer posts have to
be broken up awkwardly into multiple posts because Facebook imposes
a 420-character limit on updates.
