I have been a great fan of LangaList over the past few years. Although I already knew a lot of the content within the FREE newsletters (and the additional content in the paid version), from time to time i picked up some interesting stuff that i didn't know about.
Now that the news letters have merged with WindowsSecrets i have just read my first news letter. The content is much better (no dissrespect to Fred intended as his content was still great) with lots more materials.
I would advise people to a look and subscribe to the free newsletter and if they like it, pay for the paid version, its not that expensive for the year.
