If the opening was covered so that dust etc could not fall into the wort your beer will be fine. There is enough co2 produced to stop any o2 from oxidizing the beer and keep microbes out.
My airlock was able to sit just inside the top of the glass carboy, so there was a seal, just not airtight such as what I would have had if I used the rubber stopper. I will add a picture if possible in a future post so people can see what I mean. Essentially, the opening in the carboy that I have is small enough that the airlock didn't fall into the carboy, but large enough so that it could sit just on the inside lip of the top of it.
I did crack one beer from this batch the other day (3 days in) to see if my batch was messed up, and I have to say, I was pleasantly surprised with how good it tasted that early into being bottled!
