PopToo has been making mistakes in not being active in managing Foursquare account.
For simple reason, such as having too little time for managing PopToo project due to working for my employer, I almost ignored importance of managing Foursquare account, contrasting to my activeness in PopToo’s Twitter account.
At least, I should be aware of Foursquare Friendship Requests from our PopToo Friends and accept them for building relationships. Though many of them were sent when PopToo’s email weren’t active, making it too hard to be notified about them, it’s definitely my mistake for not being responsive.
Though it’s too late, I accepted their Friendship Requests. I just hope our PopToo Friends are much forgiving and understand some limits of PopToo project and its developer.
From now on, as PopToo’s dedicated developer, I will try to spend more time using Foursquare. This is much needed for me to learn more about Foursquare’s API, so I can bring more Foursquare related new feature for PopToo iOS App.
