Your anecdotes may be relatively worthless to a company as large as Google, but they may yet be quite valuable to an individual reading your words. Don't be afraid to share your thoughts; sometimes these smaller, more human interactions can make all the difference.
"In Internet culture, the 1% rule is a rule of thumb pertaining to participation in an internet community, stating that only 1% of the users of a website actively create new content, while the other 99% of the participants only lurk. Variants include the 1–9–90 rule (sometimes 90–9–1 principle or the 89:10:1 ratio),[1] which states that in a collaborative website such as a wiki, 90% of the participants of a community only view content, 9% of the participants edit content, and 1% of the participants actively create new content."
