Same for me. I started using Reddit because I tried Boost and it felt like a good replacement for the RSS reader I've been using. For one thing, I didn't have to look for the content places I wanna add to RSS and most have difficulty showing full-page content kinda defeated the purpose for me.

I made a Reddit account because of Boost. I didn't know web only features of Reddit because I never used web version.

I originally didn't migrate to Lemmy but kbin. Seeing Boost back for Lemmy, I followed Boost.
