My main gmail account is now over 11 and a half years old, and since then I've opened a few others for various work-related activities. None of these are close to being full, and frankly, since most of them are related to projects that are no longer active perhaps it makes sense to consolidate them in some way and make them into accessible (but rarely viewed) archives. One reason not to do this is that some of those accounts have photos that people who took part in those projects might want to view, though it's my experienced guess that "might want" probably translates to "don't really care about". It's primarily my archivist's approach to everything that keeps me from making it hard on someone who just-maybe-perhaps-sometime-in-the-not-really-foreseeable-future might want to view something.

There is, however, substantially more, and substantially older, mail in other accounts. It still occasionally happens that someone will ask about a file stored in a work account from even ten years ago and I can probably succeed in finding it. Nothing serious would happen if I couldn't, but it's nice to able to do so.
