Google Docs
Runner-up: Wikis
We didn't title this Most Popular Collaboration Tool
, because as
painful as it is, the majority of on-line collaboration tends to be
e-mail messages with subjects like "RE:Fwd:Fwd:Re: This one Re: Final
FWD: Final2"
and ugly multi-fonted .doc files. Although popular, that's definitely not
ideal. Google Docs takes the spoils of war again this year with its
ever-improving feature set for on-line collaboration. It's even possible to
watch as someone else edits a document. For everything else, wikis are
still popular. Easy to edit and easy to maintain, wikis are a godsend
for living documents.
