I follow people who I find interesting. I get notifications of posts by people I follow regardless of what groups I belong to. That takes me in new directions.

I only follow people I've meet IRL.

Yeah works you can always unfollow

As a newbie, I did not know how to adjust my account setting. Taking the plunge, I followed an apparently like-minded man.

Immediately I was buried by emails each time he posted, yawned or farted. Then he spat an anti-Democrat slur. Yikes! Quickly unfollowed him.

So, I ruthlessly tightened my account settings and stopped email alerts. Now I don't follow anyone.

I'm host of Battling Obesity and follow all its members. In addition, I follow anyone who follows me, and anyone living nearby, and others that make interesting posts, comments and replies.

ATM I follow 469 people.

Does the person make me smile is my main criteria. Then would I like to have a real face to face conversation with them. Answer yes to at least one of those, then maybe I'll follow them.
If dating happens, then all well and good. Lets just say I'm not holding my breath for that. I fear it is extremely unlikely that I'll ever get a date here or anywhere else...

if they seam cool and there female or really cool then i follow them and if there dicks they can fuck off

You follow when you appreciate/love/hate their comments ,or the way they express themselves. Very little to do with dating, if anything.

The more important question is, how do you decide who to block? I'm still debating internally over one or two whose entertainment value just barrrrely exceeds their annoyance quotient.

I just follow people who seem to have interesting points of view, and honestly, when someone follows me, I sometimes return that out of politeness if they seem interesting.

I had to look at my profile to see who I follow. I picked people who I thought might be interesting and/or challenging. There are 5 people and it turns out that I haven't had an exchange with any of them for a long time.
