I'm still using them a lot.
I even still use Feedburner, but only to style my feeds. People have been saying for years the site will disappear, yet, it is still there. And true, some of the features don't work anymore, but I haven't found a worthy, free alternative yet to add styling to my RSS feeds.
It's kinda funny: although I use RSS feed URLs for a lot of things - mainly for cross-posting, but also for things like what I talked about in this post, I'm still an old-fashioned email person myself. I only use aggregators to set up autoblogs and things like that. You'd think I would have evolved by now, but I'm still reading emails 😂
