The New Facebook Groups - All You Need To Know

Looks like groups are getting quite attractive features that pages do not have, like group notifications, group chat, documents etc.

Has anyone tried them?

I think this totally changes things. You can invite all of your friends to the group. Then mass notifications, chat. You can spam everyone in the group at once. Although if overused they will all leave the group.
I added a few thousand of my friends and I got a lot of angry emails that they were added to a group without their permission and their emails are now full of links.

It looks like you can even add people automatically who are not your friends.

I don't understand why FB will let us do this. But I have a question. Any limit for the group size? Can I create a group with more than couple thousands members.

There are groups with 1000000+ members. However, with old groups you could not message to all members after you get 5000 members. I don't know about new group rules.

The Ugly Side Of The New Facebook Groups
When Facebook released the revamped groups product yesterday, many people immediately decided to jump in head first. Unfortunately things haven't been completely smooth sailing.
Facebook Group Membership Is Opt-Out
There have been a number of complaints from users, most significantly that group membership is now opt-out. That means your friends can instantly subscribe you to noisy Facebook groups. If you woke up today and had a bunch of notifications, the main reason is probably that you were subscribed to groups by your friends who thought they were being kind. The problem is that I need to manually go in an unsubscribe from all the notifications I receive from noisy groups because my friends have added to them. This is more work for me to do!
Facebook Group Chat Cant Be Hidden
Yesterday, many users quickly realized that group chat is annoying as hell ... especially if you are a member of a large group. Suddenly your browser tab is flashing every couple of seconds to let you know that someone else has posted a message. The only way to shut off a group chat room at this point is to shut off chat all together. In other words, there's way too much noise. My guess is that Facebook will make it possible to hide a room's chat at some point.
Conversely, I've found that by popping out the Facebook chat it can suddenly become manageable in that you can hide the chat window behind other browsers. Something about this doesn't feel right though.
Facebook Groups Detract From Other Things
Groups are definitely an extremely valuable product, however the reality is that people can't consume all the content on Facebook as it exists. The result is that Facebook Pages may end up feeling the brunt of this new product, although we haven't had enough time to measure the impact. There's a chance that they won't detract, but with the amount of time I already spend on Facebook, groups will serve as another way to keep me active.
There's Definitely Value
Overall I'm actually a big fan of the Facebook groups product, however there are a few downsides to the product that can be pretty annoying. The most significant is that many users feel like some unspoken level of trust was broken when Facebook let other people add them to groups. In one sense this is how Facebook Photo tagging works, yet it was a feature that many people still feel uncomfortable about. What do you think of the new groups product? Have you used it much?

The new groups are a powerful way to build super focused groups.

But I'll be shocked if they keep these groups Opt / Out. That's been the biggest complaint and it's warranted. I was away from my desk for a couple of hours and had over a hundred emails with updates from groups I had been invited to.

It's easy enough to turn off the emails, but the default is set to receive them

These have been working out excellent for me.

LOL FB just gets stupider and stupider.

but still fan pages win over groups i think so.

How is it opt out? If you invite a member they automatically opt in?

I looked at the group feature and I like it. It lets you do things that you would not otherwise had the chance if you were using only faceboook.

Now the big problem as with all Facebook related is that the concept although good is to easily prone to manipulation. I mean I understand that they need to make money but they are exaggerating and their greed kinda shows throughout all their policies.

How do you access these new features, I created a new group and I don't see them. Also how do you add members without them opting in??

I just made a group and add 400 people. It seems very effective way to "communicate" with many people.

FACT:

After getting 5000 members into your group, you the administrator will eventually lose the capability of sending message to the members.

We have to just wait and watch for few more days .since there may be some more changes to come.

Thia is the weirdest feature that facebook came out with. Good for spammers

So, I've created a group and sent invites to my friends. But how do I make people auto subscribe like mentioned in this topic?

How is possibile to create a group and INVITE ALL the friends automatically?
Not only owner friends but also someone inside the group, I want to add all their friends automatically, possible?
