I couldn't figure out reddit for quite awhile, but now it seems pretty good.
One question - do you basically put whatever you're looking for after the r/ to see if there is any discussion of it?
Example - last week, twitter kept trending with Chuck Todd, after he did something controversial on Meet the Press. I didn't want to keep reading what the idiots on twitter had to say in 140 characters, so I went to reddit and put his name in the search box, but didn't come up with what I was looking for. Is the idea to put it after /r?
