It's surprised me how long it's taken for instant messaging (im) to catch on in the corporate world. According to the article, 4 in 10 adults use IM, but only 1 in 5 IM users use it at work. So, only about a 10% penetration rate?
Surprising it's taking so long. Among my generation, everyone uses IM. The only people I know that don't use IM are people that were spending too much time on IM, so they deleted the program.
Of course, the network isn't secure, and it can be an easy way for disgruntled employees to leak information out of the company. But it is a quick, easy and cheap way to communicate.
