Most people today start out with tabs from the net only. A book is great!

I myself started on
www.ultimate-guitar.com + pirate downloaded music.
Now, I like the challange of picking out notes from songs with just my ear and the music. I get a happy feeling when i find the right notes to fill out the riff or whatever im pickin' out.
Edit: I forgott to tell you but.
Www.Youtube.com is pretty much a complite teachers brain you can put keywords in.
