Why not?, whatever works!. I think many of us put much emphasis on the technical aspects of photography and in the process forgetting that photography is about what looks good at the end. I find that happening over and over from Nikon and Canon users and without thinking that they might be missing on something. Very often we hear Nikon and Canon users recommending their brand to newbies by saying "...because there are more lenses and accessories". Well I never bought any "accessories" nor used more than three lenses.
Do you know why is this happening?, because most Nikon and Canon users never used an Olympus but most Olympus users already used Nikon or Canon.
