I think it depends on what you are using the picture for. If you are posting a photograph for a critique of its photographic qualities, then a border is a distraction that takes away from that purpose. If though, you are using a border as part of the final presentation of a photograph, then that is as much part of your artistic/personal decisions as was your composition in the viewfinder when you took it. In that regard, borders are similar to matting when you frame a picture. The matting or border can help, or detract from the picture. However, if it suits how you wanted to present it, then it isn't really "wrong".
