I sort of do - I use Microsoft OneNote to track all of my quilts. I have a table that I use to track the quilt name, start date, finish date, and where it ended up (kept, or if given away who I gave it to). Then each quilt gets their own little section where I stick stuff like pattern info from EQ7 (since I make all my own patterns), sometimes scans of graph paper drawings, info about batting type, any special notes or techniques I tried, a photo or two of the finished quilt, etc.
I also have a separate chart where I track my work in progress...tick off when I've got pieces cut, when I've got the top built, when I've got the binding and backing prepped, when I got it sandwiched, bound, quilted, etc. So at a glance I can see how many projects I have in progress and how far I've gotten on each of them.
I like it, but I was really touched by being able to leaf through my grandmother's quilt journal. There's something special about having it on paper....maybe that's something the next generation(s) won't feel but it makes me want to do a paper version too.
