Bookworm in the City

Blurbs confuse me.
They can annoy me, especially when they take up so much space that the back of a book has no summary.
They can make me suspicious if they appear on the front cover and the back alike. It makes me wonder why the book needs all these recommendations: it feels a bit like an over-eager salesperson jumping at you.
Blurbs can leave me stumped. Some books have the blurbs continued on the inside, and they can take up several (several!) pages. Three, four, pages of nothing but raving quotes just seems a tad much to me. Is there such a thing as a magic number for blurbs?
And sometimes blurbs surprise me, with names of people I don’t know. I do tend to look these people up, after I finished the book and agree with what they said because I’ll reason that if we liked the same book, they might have published something themselves that I might like. Is that why blurbs exist? To sell us other books?
