I’ve not seen or heard of any such blog, so I can’t speak about that.  As for the Canterlot Wedding, I think it was good.  It had a few flaws, namely the instant inclusion of Shining Armor and Cadence without lead up, and several points of Chrysalis’s plan which paint her as overly ambitious and prideful.
I didn’t mind the ending too much, because to an extent it makes sense.  The joining of Shining’s and Cadence’s magic to create the effect that it did is often panned for not making sense, but it does to a point.  The diet of changelings and windigoes prove that within MLP canon it is possible for emotion to be channeled as energy.  On top of that, it is shown several times that magic may be boosted under times of stress (Twilight), or under the influence of certain emotions (Sombra) both of which were factors during the occasion.
Shining Armor is shown to be an incredibly competent user of barrier magic, the very thing that cast the changelings out of Canterlot, and assuming that Cadence acted as a sort of amplifier for the reasons explained above, then the ending works very well.
