Two of DC’s most well-known event and social media ladies, Lisa Byrne (@DCEventJunkie) and Melanie Spring (@Sisarina), co-hosted the second-annual Mashable Social Media Day last Thursday, June 30.

Some of our favorite twitter handles were spotted enjoying the great weather and happy hour specials in honor of the new holiday.
