I'm somewhat divided on the email alert issue. On one hand, it did used to be quite convenient to read from the email. On the other hand, that the contents of the updates were sent might have had something to do with the various email providers causing problems with message delivery. I can only imagine that part of the spam filters companies might employ is blacklisting domains that send large amounts of pornographic content, since that was one of the standard features of spam filters back in the bad old days of the spam wars. And I'd rather get the emails at all over not getting them, but them containing the entire update.
I'm wondering what exactly is causing the reports of blurry text, because while the current styles aren't ideal, they don't contain any sort of blur element, and shouldn't be doing that. I suppose it's possible if the font used is one their system badly mishandles, but it really shouldn't be. Normally I'm a poster child for vision issues, given my eye problems and all that, but none of my monitors or screens have displayed any blurring. I suppose, some screens might have haloing, where excess backlight bleed into the grey around text is a thing, but that would be an unusual problem to have manifest suddenly. Then again, I color calibrate my displays, so maybe it's an issue with edge cases on GPU color tables, alpha, or some other display settings that can't reasonably be predicted and aren't so easily solved.
I'm glad the important part of the upgrade is done with, and that it's mostly down to making it look nice again and fixing a few issues(the tab situation being possibly the most important one). I'll probably be relearning where everything is for quite some time, especially as things shift around as more changes get made.
