No, no Orthodox does not follow the pope. Whomever claimed to be Serbian Orthodox: Have you been to a single Orthodox church?
Only Roman Catholics follow the Roman Catholic Church and Pope.
If you want any more information, e-mail me. I'm rather lazy right now, and don't feel like going into a lengthy explanation. Perhaps I will add more to this answer tomorrow.
Note: There is little difference between each subset of orthodox churches.
There are a number of separate Orthodox Churches: Greek Orthodox, Russian Orthodox, etc. Each one has a Patriarch at the head of the Church organization. A Patriarch is a bishop that is above the other bishops in that Church.
The Orthodox Churches recognize the Pope as another Patriarch, the Patriarch of Rome. They do not recognize him as head of their Churches. The Roman Catholic Church recognizes the Orthodox Churches as having valid Bishops, Priests, and Deacons, and valid sacraments. These Churches were separated by historical circumstances, and have somewhat different practices and doctrines, but the essentials are the same.
The Roman Catholic Church also has members who belong to the "Eastern Rites." These are Roman Catholics, but they follow most of the practices of the Orthodox Churches, insofar as they do not contradict the beliefs of the Roman Catholic Church. These do regard the Pope as their head.
The Catholic Church split around 1054AD -- at that time many of the Eastern Churches now called Orthodox deny the primacy of jurisdiction of the Bishop of Rome (the Pope) -- to this day they still affirm a primacy of honor to the bishop of Rome. Today, the Orthodox Church is run by several bishops who share equal authority -- however, the Bishop of Constantinople is considered the so-called head of Orthodoxy. There are other popes in other apostolic Churches such as the Armenian ancient Church.
Pope = simply means papa -- a spiritual father if you will.
The Eastern Orthodox Church is not a single church but rather a family of 13 self-governing bodies, denominated by the nation in which they are located (e.g., the Greek Orthodox Church, Russian Orthodox Church, etc.). They are united in their understanding of the sacraments, doctrine, liturgy, and church government, but each administers its own affairs.
The head of each Orthodox church is called a "patriarch" or "metropolitan." The patriarch of Constantinople (Istanbul, Turkey) is considered the "ecumenical," or universal, patriarch. He is the closest thing to a counterpart to the Pope in the Roman Catholic Church. Unlike the Pope, who is known as VICARIUS FILIUS DEI (the vicar of the Son of God), the bishop of Constantinople is known as PRIMUS INTER PARES (the first amongst equals). He enjoys special honor, but he has no power to interfere with the 12 other Orthodox communions.
Orthodox and Catholics separated from one another in 1054. There are very few theological differences. The main difference is that the Orthodox Churches (http://www.newadvent.org/cathen/11329a.htm) use the Byzantine Rite (http://www.newadvent.org/cathen/04312d.htm) and the Catholic Church use the Roman or Latin Rite.
Pope John Paul II said of the Orthodox Churches in Orientale Lumen, "A particularly close link already binds us. We have almost everything in common." (see http://www.vatican.va/holy_father/john_paul_ii/apost_letters/documents/hf_jp-ii_apl_02051995_orientale-lumen_en.html )
Does the eastern orthodox catholic church go by the pope?
