Recently The Frumps (NSFW), one of the webcomics I follow, asked how its readers used its RSS feed and if we preferred having a thumbnail or a full-sized cartoon. I started writing a reply to them then realised that I wasn't just explaining how I used their RSS feed, but how I follow websites in general.
I follow quite a few RSS feeds, originally I used Google Reader but when when that closed I decided that in future I would have control of my reading and not be placed at the mercy of a third party service that could vanish at any time. Eventually I decided to use a self hosted copy of Feed-on-Feeds as my RSS aggregator. I use it for following webcomics, news (e.g. newspaper sites), science blogs, some technology bloggers I enjoy, as well as social, political and environmental bloggers. Occasionally if RSS isn't an option I'll subscribe to email notifications for a really good blog, but never (so far) to a webcomic.
