Is there any way to search for microbadges by keywords? Even the feature that breaks it down be category has so many categories that it takes forever to look through them.
Not on the site, but Google can do it. Cut-and-paste the whole line below, removing the two spaces after the 'www' part.

(Adding this link as one of your 'Quickbar' shortcuts does work, too)
