Yeah, I've read some.
I'm sorry I didn't come across his books when I was a pre-teen, I was a bigger fan of that type of writing then. I've read plenty of old-times science fiction and fantasy, stuff like Jule Verne, and all sorts of writers I don't remember, with plenty first-person narrative stories that start similarly to "You'd never believe me, but...".
Good ol' Poe was always my favorite back then, too.
But, more on topic, yeah, I've read some of the Lovecraft's books and I'm well aware of most obvious things related to his writing - and frankly, I find it charming. He's not a very good writer at times, but some of the concepts are certainly great, cosmic horror is one of my favorite "genres" to be used and abused in science fiction. (although his writing obviously isn't science fiction, but the whole genre of cosmic horror, with beings so ultimately more powerful, strange, and malevolent to humans and similar mortals, very much fits my nihilistic view of the universe. And I love things like that in science fiction, as I've said before.)
