Hello there,
Yes, I'm the owner of the Twitter account for the Gagapedia. As I'm not very active on the project lately, the twitter feed is also quite empty. I would love to see it being active again! I'm interested to see what you have in minds (taking over the Twitter, promotional events like the example with 1D, etc.). We also have a Facebook page that could use some help too ;)
Have a good day :)
