Twitter's downtime doesn't concern. I'm a lot more worried about the status of another online service: Beerhunter.ca.
The site uses Google Maps and information about the closing and opening times of LCBO and Beer stores in Ontario in real time. I told my roommate about it the other day, and although I question why he was trying to buy beer on a Wednesday morning, he described the site as "the most amazing and useful site for Torontonians."
According to this news release, the site got 30,000 unique visitors in its first three days based on word of mouth (I might be slightly biased, but I have no idea they would use "PR News Now" to issue their release).
Come back soon, Beerhunter.
