I'm probably in the minority (hey, I shoot film and print in the darkroom, I'm in the minority by definition!), but I often just use IG as a jumping off point to a photographer's or publisher's own web site, YouTube, or some other information posted outside of IG. IG is a great place to discover new things, but not the best place for more in-depth exploration.
For reference, I typically only follow fairly well-known photographers (not the cellphone selfie crowd), photobook publishers, companies producing analog-related products, a handful of camera dealers, and a small set of other photographers I've discovered on IG whose work I like. These are typically not the like/follower-driven folks who seem to dominate the platform.
