AMA, or ask me anything, is an online interview format popularised at Reddit, see [1].

The interview subject answers questions posted by members of a forum.

We hope to provide as many AMAs as possible through the end of December, 2018, as Google+ users are contemplating platform alternatives.

Plexodus / G+MM AMA format[edit]

As with most of this project, this is an evolving situation and this process will likely evolve over time. Bear with us as we sort this out.

As of 19 October 2018, AMAs are being held at the Google+ Mass Migration community, on Google+. Both interviewees and those asking questions must have a Google+ account. The AMAs can be read by anyone.

The format is text-based.

AMAs will be scheduled as live question-and-answer sessions. The AMA will start when the guest opens their post.

The AMA is self-serve. Please visit the Google+ Mass Migration forum

Guests start the interview by posting the following, replacing <name>, <role> and <project> as appropriate:

*Hello, my name is <name> and I am the <role> of <project>.  Ask me Anything!*

The asterisks will create a bold title for your post.

Please post a proof of your AMA to a Well Known Channel and link to that from your AMA.

Guests will answer questions for at least one hour following the scheduled start of the AMA. They will return for follow-up questions 4-6 hours later, if possible.

It is possible that future AMAs may be held at the Plexodus subreddit, should it provide sufficient audience.

Requested AMA subjects / topics[edit]

About Google+ and Google+ Communities[edit]

If you're interested in the Google+ Audience, here are some basic facts and figures, such as they are. Good data on Google+ activity has been hard to come by, and Google themselves have not been forthcoming. Sampling and other methods provide a basis for inference.

User and Profile Statistics[edit]

The total number of profiles on Google+ was more than 3.3 billion as of March, 2017, the last time on which these were updated, using Google's own Sitemaps files as a guide. This represents an upper bound on the user population, and appears to strongly reflect Android device registrations. Evidence suggests most users are not active.

Roughly 9% of all Google+ users have ever made a public post on the service, from its 2011 debut through late 2018. This is roughly 300 million profiles.

In 2015, Dredmorbius used Google Sitemaps and web-scraping to estimate publicly-visible activity on Google+. An independent follow-up study was made by Stone Temple Consulting based on the same methodology, which found the following (rounded to 3 significant figures):

  • Active profiles: 112 million
  • 50+ posts ever: 6.66 million
  • 50+ posts ever and active within past 30 days: 3.54 million
  • 10+ posts ever: 21.8 million
  • 5+ posts ever: 32.9 million

Within past 30 days:

  • 100+ posts: 53,300
  • 50+ posts: 106,000
  • 10+ posts: 1,960,000
  • 5+ posts: 4,390,000
  • 1+ posts: 16,000,000

Another analysis in August 2015, this based on Google Web Search results for a set of keywords, found G+ had roughly 6% the apparent total post content of Facebook, about 135% that of Reddit at the time.


There are 7.9 million Google+ Communities as of 22-23 November 2018 based on a random sampling of 12,000. Of these, 3.9 million have 1 or fewer members.

This still leaves a large number of groups from modest to very large sizes:

G+ Communities Size Distribution
Members Observed Estimated
1,000,000+ -- 54
500,000+ -- 101
100,000+ 4 2,400
10,000+ 17 10,200
1,000+ 78 46,800
500+ 70 42,000
250+ 130 78,000
125+ 192 115,200

Of the 12,000 sampled communities:

  • 8 were missing ( 0.07%)
  • 10,814 were public (90.12%)
  • 1,170 were private ( 9.75%)

A missing community is one that had been deleted between gathering sitemaps and visiting the community homepage URL.

  • 6,586 had open membership (54.88%)
  • 5,414 had closed ("ask to join") membership (45.12%)

Total membership numbers are a count of relationships between profiles and communities, not of total G+ users:

  • Total sample membership of public communities was 1,331,812 (estimated: 800 million overall).
  • Mean membership (public only): 128.67

Open communities have far higher typical membership than closed ones, unsurprisingly:

  • Total open-community membership: 1,207,115 (90.64%)
  • Total closed-community membership: 124,697 ( 9.36%)
  • Mean membership for open communities: 183.28
  • Mean membership for closed communities: 23.03

Group vitality -- real people engaged in positive and productive interactions -- is harder to judge, though spot checks suggest that active and engaged communities are fairly rare. A rule of thumb might be that ~1% of groups and within those, 1% of users, are highly engaged. This is a very rough heuristic.

Many Google+ Communities are not particularly healthy, though exceptions exist.
