I like to keep the main Philly Tech News twitter feed (@phillytechnews ) fairly compact, so I don't post info about most events on it. Since the Philly Tech News Events Calendar is rather extensive, I want to have a way to share that content with users as well.
So I've established a new, separate twitter feed, @phillytechnewsevents, which is fed automatically from Google Calendar. Events show up on the feed soon after they are added to the calendar. I'll look at finding a way to add reminders perhaps one day before an event.
Of course, you can always access the Philly Tech News Events Calendar here.
