Single-transistor OR gate

view story

http://forum.allaboutcircuits.com – A very simple question, I guess. I was looking for a simple OR gate using a transistor. Specifically I need a 8-bit OR gate which in turn will drive a transistor. So I thought it would be better just building the gate with the transistor itself. I looked around in the web for various versions of transistor-made-gates. But I couldn't find any OR gate using a single transistor. I was thinking of a circuit like this one: I think this will do. But I wander why I couldn't find something like this published. Is there something wrong with this? (Embedded)
