I find myself having to add `site:reddit.com` to an increasingly large of queries to have any useful result. I wonder if I should make a little userscript that can add it for me with a hotkey/text combination..
In Chrome, right-click the address bar and select "Manage search engines" and you can add shortcuts like "r <search term>" to search reddit, stackoverflow and wherever.
I've been working on a tool that also filters out the cruft comments from reddit / ugc searches. We just came out with a chrome extension as well. Would love your feedback on it: www.thegigabrain.com
