Like others have said, this is very much a 'it depends' kind of question - are you aiming to sell your work via a website, promote it, or just sho it off to anyone who is passing? Do you know anything at all about web design, or the things related to it such as methodology, hosting,
seo etc.
If you are a complete novice, I would hand it over to someone and say - 'I want domain xxx.com', there are the photos, and this is what I want to achieve, simply because it can take a long time to get to grips with making a half decent website. If you simply want to showcase your work with minimum fuss and outlay, you've done the best thing by joining flickr.
Like most people, I've got a vested interest in the topic, having designed an built my own photography showcase
DigitalSLRPhotos.com) and run a blog (
FlickerLister) and I'm happy to offer my services, but knowing exactly what you want to achive first and foremost is important.
