2500 Random Things About Me Too

Original post title, ho!
I always hate that these kind of books, which were written in a specific style, don't really reveal within the pages what that style is.  Or maybe they do, and I just don't notice.
Eh.
At any rate, I was pretty confused until I looked up the idea behind this book, 2500 Random Things About Me Too.  Essentially a meme that somebody continued everyday for the next forever involving exactly what the title suggests: writing 25 random things about oneself.
That being clear to me, I found the idea of the book rather interesting.  It jumps around, ranging from simple and pointless to profound and sensual.  It's didactic in a way, but because of the way the the random things flow into one another, it's also very smooth and organic.  It's very similar to Hejinian's My Life, I'd say in an even freer form.  Hejinian's seemed written for a very distinct purpose; while it's also 'scatterbrained' and somewhat distant, the poet seems to have a central idea or voice in mind.  in 2500 Random Things, it's just free-flowing mental output, as it were.
Another curious aspect is how self-aware the random things are. The small narratives are interrupted once and a while with simple observations to the reader, like, "yes, she drank a lot," "That's not heartwarming at all," "nonsense," and (ironically) "I don't like how this is starting to get narrative." The poet takes a quick moment to answer questions we may or may not have had.
Those are my thoughts for now, but I always write these things before class, and come away with more thoughts or opinions afterwards.  Should I do it after, before?  Befafter? Afterfore?
Honestly, that the book is so incredibly long seems unnecessary to me.  I like the format in which it is printed, but do we really need so many random facts? That's one thing I've never really understood about poetry in general. I like the idea of chapbooks, and a collection of one's works are fine, but a zillion pages devoted to a singular idea, or style?  Hmm.
