Microsoft owns the ideas around word processing, spreadsheet and presentation software. "I want it in a .doc" "Put it Excel" "Look, another PowerPoint!" But it need not and should not be that way.
I'll cut to the chase: if you create content in proprietary format, you will always depend upon the company that supplies the company to access your work. And as the saying goes, "if you can't fix it, you don't own it." So much more for simply opening what you've created.
Or inherited. I'm thinking about documents in the long game. Proprietary document formats are a dead end. I have files from the 1980s and 1990s I can't open; what the chance that a church archivist will open your membership list in a hundred years?
You can (and should) use plain text and comma-separatedÂ values for simple documents. I have a fun, easy and public-domain resource for presentations that I'll write up in about a week. Perhaps some will use (La)TeX for graduate theses andÂ dissertations. (Right, mathematicians?)
And for more complex, but everyday tasks of word processing, spreadsheet and presentations, please use the Open Document Format. The world of open format advocates are celebrating Document Freedom Day today.
You can participate by considering how your casual document format choices have limited your access -- like sending or having been sent one of those .docx files -- and considering your options. The Open Document Format (ODF) is used in Google Docs, and the mature and free (both in licencing and cost) office suites OpenOffice.org and its continuing spin-off LibreOffice. (These can also read the proprietary formats, so I'm not setting you adrift.)
Use those formats, please -- and I'll make the pledge. If I need to put a word processing document or spreadsheet on my blog, I'll make it available in ODF.

Later. Jeremy Carbaugh, a colleague in the Sunlight Foundation Sunlight Labs team, was the one who told me about Document Freedom Day, and he also wrote about it. Sunlight makes a similar pledge about publishing these kinds of documents additionally in ODF.
