Challenges are all the rage!

Reading challenges seem to be what people are doing in 2008. I'm not really tempted myself, feels a bit too much like a reading curriculum, but I admire the organisational skills of those who do.

• Kari over at Another Book on the Stack is undertaking no less than 8 challenges and has so far identified 48 books and is even organised enough to cross one off so far.
• I know Marg at Reading Adventures is into Challenges too. The ones that Marg is doing so far include the Chunkster Challenge, the Romance Reading, the PulitzerProject, the ManBooker, Pub08, and Sci- Fi experience, and I get the feeling she is still looking. Perhaps she'll tell me how many books that is.
• Friend Sally has listed the challenges she is undertaking at her Reading Challenges blog. Looks like she is doing 15 or so challenges. Her list of the challenges she completed in 2007 is impressive

Here are some others you might think about - until I began searching I didn't expect to find so many!

• Book Awards
• Short Story
• A Novel Challenge - contains lots of lists to investigate
• Reading Dangerously
• Notable Books
• YA
• A-Z
• TBR
  

So, are you into Challenges?Tell us about the ones doing this year.
If you are, why do you do it?
Are there any specifically for crime/mystery fiction readers or do you just make up your own list?
Or perhaps you can try to convince me that I should join one or two!
