Less than one-half of online Americans would be extremely interested or very interested in using cloud services, according to a poll from Harris Interactive. Nearly one-third (31 percent) would not be interested at all. The ser

vice respondents are most interested in using is also the most established: email. Services they are least interested in using are financial services (53 percent).

As with everything tech, the willingness to use the cloud becomes more positive the younger the demographic trends.

The biggest concern is of course security. Eighty-one percent of respondents are concerned with security, and 84 percent said they would continue to save data and documents to physical storage devices. And only 25 percent would trust cloud services with their personal information.

Thirty-eighty percent would not be interested in the cloud because it sounds too complicated to use. And that’s perhaps one of the big obstacles to the cloud – “cloud computing” gives the idea that it is radically different than the computing that users already do.

It’s strange that we continue to talk about this strange entity called the cloud, seeing as how so many users are already comfortably there. People are already spending most of their computing time in the cloud, and a lot of their data is already there.

If the sweeping changes that Facebook announced at yesterday’s f8 developer conference are successful, users will become more open to having their data and personal content all over the internet.
