I don't even use LO that much, and I'm panic saving in cycle every time I do because it crashes of me so often. Hell, it crashed on me this week, on a 5 pages doc with images, text, one table and a few titles. Nothing fancy.
I keep reading people saying it's stable for them, but I've was using it already when it was called OOo, before we had docx support, before docx even existed.
And it always has been this buggy.
I donate to the project, I report bugs, I keep advising people to use it.
But still, either I'm incredibly unlucky, or people are just ignoring all the crashes and became blind to them.
Which is a phenomenon I'm seeing a lot in the FOSS world: power users just don't see the bugs anymore because they work around them to easily and effortlessly, almost automatically. It doesn't help getting the software to a better state, nor does it inspire confidence to the new comers we oversell stability to.
So really, really, like the last 10 times you used LO, are you sure there was no problem at all?
