I've seen the 5-minute workshop done in person and it was terrific. I don't think that this website does justification to the process, which is quite good. I think that if you are familiar with the TLT group, this is a fine resource. If this is new to you, it's tough to process.
I had to do a lot of clicking to find information.
Time spent reviewing site:
10 minutes this time, but I was already familiar with the site and the content.
