Big Data. That's the new thing in Information Management.

Yup. A lot of it is ease of use and a lot is, "we've got the capacity, so why not"? At work we used to have a pretty small email server and used Thunderbird, so you would be forced at some point to either delete emails or move them to local mail. Now we're on Google Government Gmail, with practically unlimited capacity. Hardly anyone bothers to clean out their mail anymore.
I was just part of a FOIA, and because I still try to keep my email in order (partially because I'm paranoid) I ended up with a couple hundred emails to submit. One of the other people in the FOIA had 4000(!!!) emails to submit over the same time period because he had no reason to clean up his emails, so the search algorithm found tons of flagged keywords in his account.
Google and "The Cloud" in general make our online lives easier, but at the same time it's kinda scary to think about all your info sitting "out there" with information stored looking like it's never going to surpass increases in storage capacity. Especially considering how few people pre-encrypt before they store stuff on the cloud, because, hey, The Cloud encrypts for you!
