Haha awesome. Looks like it's a video game-related document (I see "Video Game Title" towards the left side of the page).
I literally just started reading comics 2 weeks ago so I'll tell you what I did personally. I started with DC Comics because they rebooted their entire line last year. Most of their series are currently on issue #4 or #5, so it's super easy to pick a few comics that you enjoy and get into them. My favorite ones so far are Batman, Wonder Woman, Justice League, and I, Vampire.
With Marvel I've just been reading a lot of their older stuff, I'm not really buying any of their ongoing issues because I don't know where to jump in. I will say that Amazing Spider-Man had a fun issue this week so I think I may stick with it.
In fact I would suggest buying old trade paperbacks (a collection of ~6 issues into one book) from series that you think are interesting, and then see if you enjoy them or not. You can buy a lot of them on Amazon for cheap. The Avengers is a fun comic but I wouldn't know what the best point to jump in is, maybe someone here can point you in the right direction. I bought the first two trades of X-Force and I'm really enjoying it, so maybe check that out? Each trade is going for ~$10 on Amazon.
Other series that I liked were American Vampire and Fables. American Vampire is written by the same guy who is currently writing Batman, he's pretty good. It's a vampire story set in 1925 Los Angeles, so it's a fun read. Fables is about fairy tale characters that live in modern day New York and hide their nature from human beings. It's a refreshing take on the genre. It's up to issue 120 though or something, so I'm starting from the beginning, but it will take ages to catch up so this might not be the best option for you.
I'm kind of just rambling here so I'll just stop now.
I second almost everything you've said here, and it's kinda fascinating to see how new readers get into comics too.
Most importantly, you're dead on the money that Trade Paperbacks are the best way in. I would never advise new readers to start reading single issues (or floppies) though. They're more for total addicts that need to support themselves week to week. For new readers, buying a series in collections just makes so much more sense. It's a more satisfying experience and it's much cheaper, especially if you're reading the classics or buying online.
The new DC books are fantastic and the recommendations above are all good. And luckily, all the trade paperbacks will be available soon so you're really best off waiting for them to get started with DC.
But then again, there are decades of AMAZING comics out there already. Books that defined modern comics like Sandman and Batman Year One and Watchmen and Preacher. Basically, anything by Neil Gaiman, Frank Miller (pre 2000s) and Alan Moore will see you in good stead. And then when you get used to the medium you can dig into Grant Morrison, that's the real shit
And even books by the best modern guys, like Jonathan Hickman and Scott Snyder and Jeff Lemire...
Man, there is so much, it's super bewildering at first. I don't even know where to start with recommendations... actually, here's a weird one - as soon as you can, read Top Ten by Alan Moore. It's amazing, it's self contained and it's very funny and serious at the same time. It doesn't often get mentioned in these kinds of conversations but it's a great intro to comics.
Actually this is interesting. ComicsGAF - what are some interesting, leftfield introductions to the industry outside of the usual Watchmen/Dark Knight/Hush recommendations?
