I did a post recently for Mashable called “40 Great Resources for Making Lists” where I covered a slew of services that bring smiles to the faces of anal retentive types like myself. As with any post on a big blog, there were a bunch of great links shared in the comments. I’ve combined my 40 links with the ones shared in the comments along with new ones that I’ve found since the post went to press. So, consider this List Master the ultimate list of list services. 
We like to keep all kinds of lists; wish lists, checklists, lists of lists… you get the picture. In this roundup we will focus on services specializing in wish lists (things we want) and checklists (things we want to get done). Using these mobile and web-based tools you can keep track of daily tasks, build your reading list, organize your holiday gift giving, and more.
***Now in Alphabetical order!***
