Since @Shrike 3 mentioned pixie-styx and D3wdr0p,

(though I don't know if I would personally recommend D3wdrop's brochure as anything other than an interesting read)

(...and also cut themself off! i implore you, release the whole list -- the more paragraphs about classpecting there are, the better! ^u^)

I feel obliged to recommend Ouroborista's Treatise on Classpecting to anyone who hasn't already read it. One of my favourites! They make some very interesting, technical analyses of the functions of the classes and aspects. Definitely worth a read.

Also, a currently in-progress classpecting blog that I want to share is Land of Classpects and Analysis. They've written at length about half of the classes and a few dozen classpects, and it's all lovely. I was deeply moved by their descriptions of some of the classes that didn't even describe me!

Classpecting yourself is a fun journey! Always remember to bring a waterbottle and not trust a quiz over your own judgement :3
