Very randomly following links I've been hitting a lot of upgraded blogs - as you'd expect.
On a couple, I noticed cryptic stuff like "Yea well followed this guide but things went to crap but I fixed it" or posts such as "Ran into a few issues but caught them. Will watch to see if others do". I've left a couple of polite comments - if you see similar, if you don't want to comment there, please drop me an email.
Do not post their url here and say anything negative though.
I'd just like to gather as much knowledge for people as we can.
