Harkle & Lonely Girl
Harkle is a new search engine that has been launched, to search captioned video / audio on the net. From the adverts at the end, presumably funding being raised through Revver
Deaf people looking at Harkle, often question what's the deal with the Lonely Girl vlogs. Because of inaccess means they've not followed vlogging trends, plus podcasts. Thus there's an an information gap, and it is assumed people are up to date on culture.
I'd only discovered Lonely Girl through danah's blog back in September, which is the only reason I was aware of the background and culture here. I would recommend you read should you need a context.
