Growing pet is a serious thing, so I'd like to keep the data on the cloud. That being said, if requested many times, then a version without registration is definitely fair.
My competitors include other social media post schedulers (e.g. Typefully) and I believe the market size is huge, since there're at least 20 schedulers on the market (didn't do the math, but enough for an indie hacker project IMO).
I want to focus solely on Bluesky, which is the competitive advantage since most of the schedulers do cross-platform posting, and cannot focus too much on a single platform.
More and more social media sites don't let you just follow "your friends".
They start automatically shoving suggested accounts in your face along with ads. On Instagram and FB both every 3rd or 4th post is a "suggested page". Also the algorithm has deemed that I don't need to get posts from the actual real people I follow unless I specifically go to their pages to see.
This. Old Facebook was okay. Planing parties with friends, connecting with people you haven't seen in years and so forth. But when I noticed they put suggested posts in my feed and just hiding posts from friends, it wasn't worth the time anymore. Also lot of other problems (showing off how good your life is to get likes and so forth. Just a lot of tiny issues)
I use screenbars (BenQ, Mi, etc.) and found them extremely helpful, in terms of reducing eye strain and leaving spaces for other desktop setups (I currently have no lamp on my desk).
