Re: Creator of the Pop-Up Ad Issues a Public Apology

I havent gotten a popup ad in years. Same here, mostly. I think the reason is that most browsers (or at least firefox) puts them in background tabs.

Re: (Paper) Notebook wars: Systems and Shorthand

I usually just use a pad of paper, and maintain up to 3 or so pages of scribbles on my desk. I tear off a new page as necessary, and throw away pages when all the scribbles on them are no longer relevant. When I do use notebooks though, the only thing that matters is that I can stack several of them...
