I don't think there's anything wrong with people posting about their hobbies, or what's up in their lives, even multiple times a day.

I have people that post multiple times every hour. Sometimes 8-10 times an hour for short periods. Generally it looks like reposting everything they read. They become a one person news aggregator, if by "news" we mean Facebook posts tailored for meme propagation (which means a good portion of them range from misleading to blatantly false).

I don't really use my feed, so I'm not bothered by the posts being in my feed for my own sake. I'm just a bit worried that they've become obsessed with Facebook attention to an unhealthy degree.
