I recently looked at over 850K social accounts connected to Buffer to see which platforms are seeing the most growth (in terms of follower counts). LinkedIn is leading the pack with a median annualized growth rate of around 18%, and Facebook is at 0%, with only 43% of accounts showing any growth.

This was a great reading year for me. Thanks to @buffer.com's generous book reimbursement program I was able to read 26 books, 19 of which were fiction. In the thread below I'll share my three favorites of the year.

My 2025 year in review from @buffer.com: - I was ranked exactly 115,290th in terms of posts sent this year. Really need to crack the top 100K next year 😅 - Surprisingly I was ranked in the top 15% in terms of total engagement. I'll take it! - Bluesky was my top platform 🤝

For almost a year, Sr Software Engineer @ Buffer, Arek Panek lived inside one of the most stubborn product mysteries at Buffer: posts getting “stuck in processing.” A tiny percentage of updates that were neither sent nor errored. Just stuck. This became his North Star, & he refused to let it go!

Some new @buffer.com data on engagement over on X. Premium accounts definitely get more engagement (and reach), and link posts have been getting punished for non-Premium accounts.

Last week I shared a @buffer.com leaderboard for LinkedIn posting streaks, and this week it's Threads' turn. Brandon (@bgreen.lol) absolutely crushing the rest of us with a 62 week posting streak 😮 What's next?

It's been a minute, but here's the latest @buffer.com streaks leaderboard. It doesn't change much so I'm thinking of doing something different, like ranking folks by the number of consecutive weeks in which posting goals are met. What do you all think?

This week I spent some time analyzing how posting frequency affects follower growth. This analysis of over 15 million posts from 160K profiles provides evidence that, unsurprisingly, posting frequency has a clear, positive impact on follower growth. Check out the analysis here: buff.ly/pT74Bqz

Too many teams overreact to normal metric movement. | Simon Heaton

One of the most gratifying aspects of @buffer.com achieving its all-time high in MRR is seeing the acceleration of growth. Not only is MRR higher than it has ever been, but we're growing faster than we have in a long time.

I'm way late to this, but how are #rstats people liking Positron now that it's been out for a while? RStudio still works great for me and I haven't yet found a compelling reason to switch, but I'm curious to hear what people think

It's been fascinating to see how social media channel connections have changed over the past 6 months at @buffer. Bluesky connections briefly overtook X and Threads after the election before reverting to the mean. X connections remain consistently high.

I got to chat with the incredible @rose.bsky.team this week and it was an absolute delight! 🦋🌹 My most important takeaway (apart from all the great stuff below)? It's pronounced "at" protocol. Like "Where on the internet are you at?" Wordplay, even? I could not love this platform more.

We've seen a massive increase in Bluesky accounts connected to Buffer and new posts created for Bluesky. 💙 Here are two charts with data from the last 3 months. What other data would you like us to look into?
A line graph titled 'New posts created in Buffer' spanning September to November 2024. The graph shows three platforms: Threads (yellow), Bluesky (light blue), and Mastodon (purple). Threads maintains the highest posting volume throughout, starting around 1,500 posts and gradually increasing to around 3,000 by November, with regular weekly fluctuations. Bluesky shows dramatic growth in November, jumping from about 2,000 to over 4,000 posts. Mastodon maintains the lowest but most stable volume, hovering around 500-1,000 posts throughout the period with a slight uptick in November. All three platforms show a notable increase in activity during November 2024, with Bluesky's growth being particularly dramatic.A line graph titled 'New channels connected to Buffer' showing data from September to November 2024.

As a marketer, I'm keeping an eye on alternatives to X. We have a ton of interesting data about platform adoption at Buffer. We introduced our Mastodon integration last year, followed by Threads in June and Bluesky in July. Bluesky growing the fastest at the moment. h/t @julheimer.bsky.social

Haven't checked in on what the people at @posit.co have been up to in a long while and I'm wondering what #rstats folks think about #Positron so far. Are there any features that make a switch worthwhile to a happy RStudio user?
