I like that it is not just for photography but really covers other categories such as music or video production. There are some glitches in how to use certain features of flikr which can be frustrating sometimes (but then again this could also apply any photo sharing website). The platform has helped me build my portfolio by being able to share images with people outside my network easily. It's great because you don't have to pay anyone else. This means no upfront fees! And if there were charges associated with uploading your work they would probably make sure you get paid fairly - so overall I think its an excellent way to upload content without having to go through third parties.
