Ridiculous to compare usage numbers between the two considering Facebook at that point (e.g. when they were at 100mil users) had no dominant products that its users were using every day. In other words when Facebook users went to Facebook, they really meant to.
With G+, the monthly stats are meaningless since they're probably representative of Gmail logins who accidentally click on +.
> Those are people who really meant to go to plus.google.com
I actually did that at least a couple of times last month by mistake, the G+ link is very close to the Inbox/Home link in GMail's web app. I cursed and hit the back button in a matter of seconds each and every time.
I went to G+ last week because Google requires it for the "Author" feature in search engine results (pure vanity, my blog posts will never show up in SERP). I went to G+ for thirty seconds this week to read the post about the guy who "cracked" a really lame DRM scheme. I don't consider myself an active G+ user at all, and yet I'm sure those "actions" (adding a URL to my profile and viewing a post) contributed to the 135 million, and I'm willing to bet I'm not the only one. Engagement across G+ per unique monthly visitor is almost certainly an order of magnitude smaller (by time on site, for example) than Facebook's.
Which means... unique user page views with 0 engagement metrics! Yay~
MAU and DAU are meaningless statistics. It's pure eye-views, that's all.
Show me some average aggregate visits per user per month, and I'll believe there's actually something happening (ie. the average number of times each unique user visited the site in a single month. Hint: for Facebook, this number is probably ~20-30).
Doubt it, thats easily traceable if that were the case. More than likely its due to things like Google Play and Android devices outpacing iOS devices. Plus a little Facebook kickback sprinkled in due to recent privacy and advertising changes.
