Steepster is an online tea log. My public page is: steph.steepster.com and you can register for your own account at steepster.com.
Steepster allows you to keep an online log of what tea you're drinking, along with tasting notes. I have a notebook that does this for me...plus the blog. I'm not sure which I prefer and I'm not sure if I'll keep using Steepster, but I will give it a whirl for a few days. The cool thing about steepster is that you can compare tasting notes with others.
If you're interested in knowing who is behind the site and more about its purpose, read this interview on the Tea Pages blog.
Do you use steepster? If not, do you think you would? I'm interested in knowing what you think about it. I'm undecided.
