A whole 168 people? Seems legit.

The way that this survey is misleading. It’s fairly impossible to initiate contact with somebody via email unless you know their address. It would trying to guess their mobile number. Facebook is similar to a directory so you have the advantage of looking them up. So of course Facebook will trump email on first contact.

Must people I know – and I’m not a student – don’t "email" on Facebook but will chat. Email is still a primary channel of communication.

Yes, 168 is far from a realistic sample size to start drawing conclusions and issuing statements.

What is this “email” of which you speak?

I think what the survey is highlighting is what Brian mentioned above. If you look for someone on facebook you will most likely find them and have a profile photo to hopefully verify you have the correct person. Even if you preform a google search on a name, facebook results are usually within the top 5 links
The same can be said for Linkedin

Interesting. I would have thought that students would have been encouraged to have a linked in page set up in order for them to acquire employment.

Any one on Google yet?

The expression “no shit sherlock” springs to mind

No one in my year sends emails, most only have an email to be able to use Facebook/social networking sites. 95-100% of my year have a Facebook.
