Every hack authoring an article and every flack penning a proposal has encountered The Question: how many users does Social Network X have? Sure, you can Google the answers, but then you run into the problem of making sure that your source is authoritative, current, and doesn’t confuse active users (those who log in at least once a month) with total users (your grandmother, who, after signing up, gave up).
Here, then, a new offering from Tech Cocktail: a continuously updated spreadsheet listing the number of active users for the big social networks, which you can see below.
Admittedly, the spreadsheet is incomplete—no StumbleUpon, no Tumblr, no Wikipedia—but that’s where part two of this project comes in: we're hoping that Tech Cocktailers will tip us to missing, and newer, stats.
So, leave a link in the comments and help us to help data fiends everywhere.
And don’t forget to bookmark the chart for future reference.
