Do you ever use OpenOffice.org?
I have a confession to make. I rarely use OpenOffice.org. I only currently use it for the table of advertisers for Libervis and occasionally for some print jobs and special docs that I don't open often. Besides the fact that AbiWord and Gnumeric, a much lighter alternatives, suit most purposes just fine, I often find plain text editors to be enough.
It seems like the only people who can really make heavy use of OOo are guys whose work is *all about* the office stuff. The book keepers, secretaries and what not. For home users it is a thing good to have available, but rarely used.
