I'm not sure what you're trying to say. I said it's one of the most buggy web applications I've ever seen. Maybe your experience differs, but I cannot see how that invalidates my experience. I don't really understand your point about complexity. It seems contradictory. You're saying other sites have most of these issues but you're also saying Facebook is much more complex without having much more issues. That doesn't make sense, especially since you're also saying you think these issues are common to what you say is a fragile technology stack under these loads (AJAX) and suggesting that it's okay to then add extra "gadgets and clickables" to an already fragile stack. With respect to your claims about Gmail, my 2 year old Gmail account currently consumes 815MB of storage across ~6K emails. I use Google Docs regularly. I have never seen the issues I listed w.r.t. Facebook on Google services. GTalk works perfectly across multiple platforms simultaneously. I even find www.gmail.com (mobile & desktop) to work better and more reliably than Apple's Mail application on my iPhone. I have never failed to attach a file to a Gmail email; I've also never failed to upload an image to Docs. Facebook's application - mobile iOS, under Safari on iOS, and on Windows - is consistently buggy. You seem pretty heavily invested in defending Facebook in such a way that you take my observations as personal attacks. Are you currently employed there or have you been employed there by any chance? Or are you a non-native English speaker?
