Visiting bookmarked blogs became too cumbersome for me years ago. I switched to Netvibes as my home page, with RSS feed widgets. That felt clunky, and I switched to Google Reader. I'm still on Google Reader (where I frequently add and remove feeds as I find new interesting sites and remove the ones that produce drivel or content overload). Regarding content overload, on a number of bigger blogs I switched to following the PostRank "best" RSS feed for them just so I wouldn't get flooded. That wasn't enough, so I dropped a lot of the big sites (in one case I felt their good content was just sourced from Reddit anyway.) Currently I still use GReader a lot, but more and more often I find good content via my twitter stream, which acts as a quality filter and as a source of fresh content. I do not get much off of Facebook, but I can see the same exact use case as how I use twitter for finding content. To answer the question my guess is yes, people use RSS less and rely more on twitter/facebook/digg/reddit/etc because they provide more diverse content, but still relevant to an individual's interests, and naturally filtered for quality.
