There's a reason I'm currently not active on Mastodon.

Focus is one of the key reasons I'm making significant progress in my limited available time as a dad, full-time employee, and side-projects addict. I rather spent time on a single platform and do that well instead of splitting time with low quality on both.

I could start cross-posting tweets on Mastodon, but I would have to invest time to reply and contribute to replies. On top of that, I've got all kinds of automation running to post tweets based on events that wouldn't work out of the box on Mastodon.

I'm sure I'm disappointing some of you, but I must pick my battles. With a 352.5% growth in Twitter profile visits over the past 28 days, I also don't have a reason to switch focus. Never say never, but until I have more time, I'll trust the strategy of focus that constantly pays off.
