I signed up to Snupps to keep track of my collection. It is much more portable than swatch sticks and I can look up in store. Although my not perfectly colour balanced and what with screen settings and lighting differences, they colours are not 100%, it reminds me of what I have it keeps my impulse buys under control. :)
I'm on Snupps as "wug". This is the nail polish I added to my shelves that saw my follower numbers explode.
It does look pretty impressive, doesn't? Check out my Snupps account to see the collection of polish I'm growing (responsibly) in London!
