We launched Quotebacks just over a month ago and it had a good reception on HN (https://news.ycombinator.com/item?id=234681750) so I'm posting here with a little update.
1) The #1 feature request is here: the Firefox extension!
2) We added a web-generator and bookmarklet for folks who want to use them without installing an extension.
Thanks for the support!
