I've got some info on the website of Webup8 for adding a ppa from Libreoffice to the system (11.04) in order to get the latest, more stable version, of LibreOffice. 

I've done that, and I'm pleased with the outcome. But I gave this as a tip on the Dutch Forum, and they received it as highly dangerous and risky. 

I stay within logics: a new version (read an updated version) of LibreOffice (3.3.3) can't be so unstable that Ubuntu (the OS itself) will crash or do some strange things. (?)

I compare it with Windows: there you have the same issue with upgrading/ updating LibreOffice regardless what it can do with Windows itself. Or am I wrong with this comparison? 

I see that it is for people whom use the office package professionally, as a more reliable way for getting a more stable version of Liberoffice. 

How is your point of view for this matter?
