Kind of, but not for all the teas. I make most notes for puerh, not because it's my favorite (by far it's not), but because there are too many samples of various brands, years, styles... You've got to take advantages of puerh samples by remembering how good or bad each of them is
But I use excel file entries most of the time and keep each entry very simple with only a few words.
Sometimes I write lengthy blogs, mainly to record pictures and make comments other than the taste. I do tealogs on steepster too, mostly when I hold a cup of tea and don't have anything else to do
