I've always disliked pdfs - they just seem too, i don't know, obscure or scrambly/messy, maybe? However, i have recently seriously considered beginning to archive instead of bookmarking. I would prefer archiving as plain text (for easier searching and compressing, etc.)...but enough content that i consume (and wish to archive) contains media (mostly imagery, not really much video), so i guess printing to pdf is more convenient for the "capture" phase. The one concern i have is storage...I mean how much storage would bloated pdfs have to use up i wonder (as opposed to, say, leaner plain text)?? Legitimate concern, not trying to be facetious. I've also heard there's some sort of web archive file format - .warc or something? If so, i hope that becomes an established thing - maybe bst of all worlds...at least for this archiving use-case.
