It seems like an awful lot of Lutherans end up Orthodox. Is there some parallel between their religion and the OC that would lead so many to embrace the Orthodoxy?
Originally coming from Lutheranism myself, I can only say the following: Luther's idea was to restore original Christianity, as it was before Rome changed some things. Due to the lack of information available at his time, he failed of course. But some Lutherans still take that original idea seriously, and thus they develop an interest in the Old Church or go as far as joining the Orthodox Church.
Here in Germany, many conservative Lutherans are also quite liturgical (and every Lutheran service is supposed to be structered - nothing really informal there) , that includes both "high church Lutherans" and confessional Lutherans. The probably most "high-ranking" German convert is Karl Christian Felmy, who is the son of a High Church Lutheran pastor.
Karl Christian Felmy himself used to be professor of Lutheran theology and dean of a Lutheran theological faculty. In his academical work, he published a lot about Orthodox matters, and four years after retiring, he became Orthodox.
Actually, most converts here seem to have been Lutheran before, at least the ones who were actively religious before. Roman Catholics who are dissatisfied with their local parish (and most of their parishes are quite Cafeteria Catholic) rather tend to join the Tridentine Rite, Opus Dei, Neocatechumenal Way or even the Uniates.
