But when you are intending to send a private message to a friend, you may look for a message button or link on their profile. But you will never find one. That doesn’t mean you can sent a message to your friend.

You can send a private message to any of your friends in Google + just by posting the message to you Stream but be careful to choose the friend from the box below you message. For a clear idea check out the following screenshot.

Also you can add a person to your share list by just mentioning them using ‘@’ before there name. See screenshot below.

Also you can send a private message to a list of friends or to any particular circle of friends. When you share the message it will be displayed in you stream.

Seeing the private message on your stream may have disturbed you. Anyway I didn’t find it cool. But relax, its just visible to you and the friend(s) you mention in the share list.

Anyhow this messaging system doesn’t work as well organized system. Its just like you updated something which is visible to the friends you mentioned. The cons of this system is you cannot recover the whole conversation history with any of you friends as we can do in Facebook or any messaging system. Also the recipient cannot replay to your message as it is actually not a message but an update. So what the recipient can do is comment on your update to respond.

Founded in a Harvard dorm room in 2004 by the now 27-year-old Mark Zuckerberg, Facebook threatens Internet companies like Google Inc and Yahoo Inc as it becomes a popular online destination for Web surfers and an important marketing channel for advertisers.

Facebook currently has more than 500 Million users. Facebook was valued at $50 billion earlier this year when Goldman Sachs invested in the company. Facebook is expected to generate roughly $4 billion in advertising revenue in 2011, up from $1.86 billion a year earlier, according to market research firm eMarketer.

Skype is an internet phone company. Last year Skype-to-Skype calls accounted for 13% of all international call minutes in 2009; of the 406 billion international call minutes, a total of 54 billion were used by Skype calls.

The blog reports that his new house has a privacy wall, a saltwater pool and a gazebo with a fireplace. Inside this lavished exterior Zuckerberg has 5 bedrooms with 5 bathrooms and 2 half-bath rooms.

If you use a computer on a daily basis then it is highly likely that you already use e-commerce software, perhaps without knowing you do. To put it in the most simple terms, e-commerce is the buying and selling of products, including services, over electronic systems. Normally this means the internet, but it can also be done over other computer networks.

You will be aware of the widespread use of the internet, which has also made its influence felt in trade and commerce. The amount of trade that happens electronically has grown by a significant amount. In order for the concept of e-commerce to work it relies on a number of other things, which include electronic fund transfers, internet marketing and online transaction processing to name but a few.

When we talk about buying and selling things, we aren’t actually just referring to physical products. You may be surprised to learn that a large percentage of the e-commerce that takes places is actually for virtual items, including things such as website domains. Of course, for anyone who’s bought something from Amazon, we all know that physical products are also bought and sold a lot online. You will notice that pretty much all of your favorite high street shops also have an e-commerce outlet. Online retailers like this are often known as e-tailors.

For the general public, e-commerce has made a big difference to the way we purchase things. It clearly makes life a lot easier for us if we know that we can buy what we need while sitting at a computer, without having to find the time to get out and about. Even farmers in the remote wilds of Iceland, who previously had no access to the consumer delights that most of us enjoy, have been known to exclaim, “What an amazing thing this internet is. I can order anything I like and a few months later it turns up at my door!” We may not have to wait so long for our parcels to wing their way to our doors, but e-commerce has still revolutionized retail.

A lot of e-commerce also takes place between businesses and when this occurs it is known as B2B, or business-to-business commerce. This is what a company like Amazon.com uses when it buys its stock for the warehouses.

So, as you can see e-commerce is a big part of all of our lives and is a very accessible idea that we all use daily, sometimes without even knowing it.
