I feel your pain! Here's my criteria for culling titles from my subscription list:

If I love the title so much that I can easily see myself pulling the books out of the boxes again years later to re-read them, then I'll keep buying them. If I know I'll never read the title again, I drop the series from my subscription list. Looking at your list, are you really going to be thrilled to re-read Venom in 5-10 years?

(I apply the same tactic to my "real" books whenever my bookcases get too full.)

Case in point: Based on what I've read so far, I think I can see myself re-reading the new Animal Man and Swamp Thing books a few years from now ... the new Flash, probably not. (DISCLAIMER: To Each His/Her Own!)

The first time I "culled" ... the decisions seemed hard. It's a lot harder to "cull" a series you've read for years ... but I suspect in a lot of cases, you're buying the book out of loyalty or in hopes the title "will get good again." Do you really THRILL to the current X-Men and Wolverine comics, or are you buying them out of habit?

This is admittedly HARD the first time you do it. When I quit buying Uncanny X-Men years (decades?) ago around issue #215-ish ... I felt like I was commiting some kind of crime. I retrospect, I see I spent about 2 or more years buying comics that I really didn't enjoy. Granted, back then comics were a hell of a lot less expensive than today! At $2.99-$3.99 a pop today, the cost of mediocre (or even bad 0 comics adds up fast!

Here's another trick ... what books are always at the top of your read stack, and which ones always fall to the bottom? Cut those books that always wind up at the bottom!

In a lot of cases, I find I can sell the books I "culled" on eBay and make some of my money back (if not all of it or more every now and then).

Trust me, as a long time home owner ... you are going to NEED that extra cash for a myriad of issue that come with being a home owner!

My first comic books: Superboy and the Legion of Super Heroes #202 and Kamandi, the Last Boy on Earth #23.  What a great way to start!
