How many members does r/esp32 have?

Is r/esp32 growing?
We don't have 30 days of snapshot history for r/esp32 yet, so we're not going to invent a growth number. We've been tracking it since Sep 6; the chart fills in as history accumulates.
How active is r/esp32?
Around 12.4 posts per day, measured from the newest 100 posts on Reddit, which span 8.0 days. Posting rate matters more than subscriber count when you're deciding where to spend your time — it determines how long your comment stays visible.
When was r/esp32 created?
r/esp32 was founded in December 2015 and is a public — anyone can post community. Age matters: an older community with steady growth has survived Reddit's moderation churn; a young one with a spike may not.
Who posts in r/esp32?
Of the last 100 posts we sampled, 92% came from distinct accounts; the newest was published Sep 6. A low share means a feed dominated by a handful of accounts (bots, mods, or one prolific poster) rather than a community.
Can I promote my product in r/esp32?
We don't have a promo-tolerance read for r/esp32 yet. Default to the safe approach: read the sidebar rules, contribute in threads where you gain nothing, and mention your product only when it is the honest answer to someone's question.
