I've hated Microsoft Excel for some time now...and I just thought I'd share reason #427,665 to hate it. The default behavior for new documents creates 3 sheets. In the majority of spreadsheets, people don't use or need the other two sheets (most Excel documents turn out to be a single sheet). In fact, I'd speculate that the average Excel user doesn't even know that there can be multiple sheets in a single document.
Hey! Microsoft! This behavior is totally unnecessary! It forces me to go over and check out the other sheets, just in case somebody put something over there surreptitiously.
You'd think it silly if MS Word created 3-page documents by default, right? Then why this Excel craziness?
