Dear Peter,
You will only appreciate Education Day if you go with an open mind--even if you end up not likeing it, I guarantee you will appreciate the massive effort that is going into promoting Orthodoxy. Last year was my first Ed Day but I did not get the chance to participate in any of the events because I was busy working in the bookstore.
I don't even know what the people who are giving talks are talking about so I really can't help you there. Frederica isn't my cup of tea but she's a dynamic speaker, and I think that St Vlad's theologians can hold their own when it comes to discussing tradition (after all, the patristics scholar Fr. John Behr has given talks at Jordanville so he can't be that bad, right?!) lol.
Peter John Gillquest is a pretty awesome guy--I live in the same building as him and can tell you he's a solid guy. Very down to earth and sincere. I don't know him well enough to tell you his theological views but I can tell you he is a solid Christian.
Despite my screwed up ecclesial status, I consider myself more "traditional" in praxis that most other folks at St V's but I generally like the classes and see no hints of "modernism" here theologically speaking. Perhaps Orthodox modernism is defined as different than Catholic modernism, but having experienced the later, I can tell you that if that is the criteria, that Orthodox modernism does not exist at St Vlad's. For instance, no professor at St Vlad's denies any of the ecumenical councils, the Trinity, the Incarnation, Physical Resurrection of Christ, that the Bible is God's Word, etc etc etc.
I think you should come and see. If you don't like it then at least you can say to people "I have been and this is what I did not like."
Make sure to witness the Hierarchical Liturgy--it was awesome last year, and I have no doubt it will be again this year.
The day ends with Vespers in the Chapel.
You will also get the chance to meet many, many wonderful Orthodox Christians.
If you decide to go, email me and let me know so I can look out for you.
As far as Jordanville goes, I myself wish to visit but remember, you can visit there anytime. They have many lectures each year.
