Looking at some of the comments, it seems that a few people don't seem to get Anonymous. Anonymous isn't a group, really - they don't have a common agenda, they don't have common opinions or necessarily common skills. Rather, Anonymous is a label people have claimed and since it seems to be a similar type of person each time (e.g. from a certain part of the Internet, hacks sites or brings them down, may be vigilantes or may well be trolling), people still hold the misconception that they are somehow a unified group. They're not. Anonymous are anonymous. That's the point. There is no link between anything they do except people copycatting each other, and using the label. Thus Anonymous is not a group - I would say it is more of a phenomenon that has arisen, with the help of the Internet.

Hmm. I use Gmail, and even though the search on Gmail is pretty good, I still file my emails. Why? Because I use my Inbox very much like an in-tray - I leave emails in it that are yet to be dealt with, and anything that is not immediately important I file away. This leaves my inbox less cluttered, and makes it very clear what still needs replying to or otherwise dealing with, without me having to write it in a to-do list. It also looks aesthetically pleasing and makes me feel overall less stressed about my emails when I can see how many need dealing with all at once, but I guess that's more personal preference. Not to mention the other points raised such as usability for shared accounts. Ultimately, though, I think everyone has their preferred way of dealing with emails, and if you're after efficiency your best bet is just to let them get on with it.
