I found that WordPress is a good platform to work with, however it isn’t like others that i have used such as Instagram. But they have there differences, where as WordPress is more of a blog website and Instagram is simply a photography platform. WordPress allows you to explain more about the work you are posting where as Instagram doesn’t allow this as much. WordPress could be a good platform to start a business on to explain more of what you are doing with your work where as Instagram is more for the promotion of your work.
I haven’t personally used any other platforms such as Wix, Weebly or Flickr, but i have looked into them and from what i can see my personal preference would be to use WordPress and Instagram as the others seem to be personal websites rather then blogs. And for me personally at this time i could find that quite difficult to keep it up to date.
