Just read up on my lovely friends data analysis of his 2011 year in Coffee (Indie Coffee Blog)
I do wonder how much I actually spend on Coffee consumption.... (maybe you'll see a report in 2012)...
For now it's just me a my notebook:
How many coffees do you consume in a day?
How much do you spend in a day/week/month/year?
Along with collecting all my coffee bags - I'll check out Daytum.
PS: what ghastly things will you be up today - it's Friday the 13th....
