There a few Facebook types that annoy me. Not specific people, but broad areas of people. What types annoy you?
Several years ago I did a Facebook cleaning and got it down to a very small number of people. It's grown again, and before I do something rash and wipe out 3/4 of my friends list like I did last time, I'm going to attempt a cathartic list of annoyances. There are at least a few people (or 20+) in each of these groups. Again, not singling anyone out and in no particular order.
Bible quoters - Do they expect people to read a quote, have an epiphany, and ask them how to get closer to God?
Pyramid schemers - No, I don't want to go to your "party" and buy the useless crap you're hawking. I don't want to see your daily or even more frequent posts about how your chosen pyramid scheme has changed your life.
Political posts - I'm liberal, but I don't like seeing posts from either extreme. I'm not going to change anyone's mind politically; they're not going to change mine. I don't even find the ones that are intended to be funny as anything other than propaganda.
Selfies/pictures of your child 2+ times per day (only exception is before/after pics like hair cuts and other transformations) on a regular basis - I know, your child has done 12 cute things between breakfast and lunch. Put them in the baby book instead. As for selfies, print them out and line your bedroom with them instead. You'll soon have your dream of looking at yourself as much as you want. I think 2 selfies/kid pics per WEEK is a reasonable number, outside of a batch upload.
Perpetual pity party people - Crap happens to everyone, but when "woe is me" outnumber interesting observations/polls/neutral/happy posts, I wish I could send some Prozac virtually.
GoFundMes - Actually these are specific posts and not people, but they are annoying nonetheless. Yes, there is legitimate need out there. As a liberal, I think the government should play an active role in objectively determining need based on a rubric and re-distributing wealth. It's not a perfect system, but sorting through hundreds of sob stories is emotionally wearing, not productive, and makes me think of all of these questions that I'd like answered before I even consider giving money. For example, if someone is collecting money for legal fees to get custody of their kids, I want to know how custody was lost originally, the facts in that case, what has changed, is the person worthy of having custody, what's the other side of the story, etc.
