can sign up for acct with unverified email addr

could use curl, python, etc. to send token instead of haproxy

http-request add-header cookie "csrftoken=...; sessionid=..." if { hdr(host) api.www.documentcloud.org }

could use curl, etc. instead of ftp (tnftp)

yy059 is a filter that prints JSON left justified according to personal preference

could use jq, etc. instead of yy059

could use a temp file instead of tmux buffers

verdict: documentcloud.org is a welcome alternative to proprietary algo search engines and opinionated news, not to mention ads and tracking

interesting fact: the site actually offers a free "scraping service" if sign up (not for me; dont like python)
