Coffee Grounds In Compost

I've been composting coffee grounds for a long time.

It takes me about 3 weeks to accumulate this much:

I'm sure there will be research indicating it's not the best thing to add to our gardens. Yet, I have not experienced anything other than rewards using it.

I use a Bodum/French Press and enjoy not impacting the heaps of waste when it comes to the recent use of coffee toss away pods. In my dual batch rolling composter, I get great compost after 6 weeks in the summer. Having a sniff of the finished compost, there's no trace of the coffee aroma left. My plants seem not to mind at all!

What I can't understand is why I've only seen one program which uses coffee grounds from big coffee shop chains.

I happened upon Grounds To Gardens at Cloverdale Mall this past April. Stopping to see bags of compost mixed with coffee grounds available for sale. My first reaction: "It's about time!"  Oddly enough, I can't seem to find it available since.

Can't see why?  Know of any?
