The internet is meant to connect people and while endless streams of information are nice, there is nothing quite like socialization. Online chat sites allow people to meet online through various manners and talk about whatever it is that interests them. Sometimes online chatrooms have topics and other times they are meet-ups for friends. No matter the purpose of the chatroom or who is in it, you still need to have one to even get started. For those that are interested in meeting people at random, websites such as Omegle.com are the best for you. If you want to be isolated with your friends on an invite only basis then Tinychat.com will serve your purposes. Then if you want as large and diverse a chatroom as possible then websites like Chatroll.com will do. There are a lot more online chat sites out there but these are some of the best.
Omegle.com works by pairing you at random with a stranger. You can input interests if you prefer or just go completely random. By putting in interests you can find people who are interested in the same things as you. Omegle.com will then sort through other users who have put in the same interests and try to pair you up. If you find yourself unhappy with your chat partner then you can disconnect with them at any time and find a new random chat partner. Omegle.com is definitely not for kids though as there is a lot of lewd behavior and crass language. Some partners might be fine but given the broad spectrum of who you may run into on a website like Omegle.com it is best to be a preteen with supervision or an adult.
There is not much to say about Tinychat.com. It is as straightforward and simple as the concept can be. You go to the website, create an account, make a chatroom, and then invite your friends to it. Anyone you invite does not even need an account; you can just invite them with a custom link to your chatroom provided to you. Its greatest boon and only downside is that random strangers cannot just enter your chatroom. This makes it great for people of all ages.
When you think of traditional chatrooms where people from all over the internet enter a single room and talk to each other then you are thinking of what Chatroll.com offers. An age old idea is put into good use with a simple interface and easy to navigate website. You can join chatrooms that interest you or even create your own which others will then be able to see and join.
