I used it to look up information regarding some of my yarn tonight. I have two hanks of dyed-by-me Icon yarn, which is merino/camel/silk. I discovered that the Ravelry database has only two completed projects with this yarn, and very little in the way of inspiration or explanation. So, as I have just used that database, I added my little Icon yarn datum to it.
I still need to find a patten that I like, though... Back to Ravelry.
