Do one reading a week with your primary deck and post it. That is the basic idea of this study, called "Primary Deck Reflections". You can read about it here:http://www.tarotforum.net/showthread.php?t=110445&page=1&pp=50
This way you have one deck that you reflect on weekly while still using all your other decks. I can tell you right now that my primary deck is going to change more than once during this year, probably more than two or three times. I like the idea of making a commitment to post one reading a week. There are weeks when I only do daily draws and this commitment will help me stretch a little. The thing I'm not so sure about is that I don't tend to do my readings on neutral topics, they are often personal and not stuff I'd want to share in a blog. I'll have to see how it goes.
