I have one, but keep letting the pro version lapse since no one follows it.
Many more people will see my new photos when I post to FB.
My flickr link is below.
One reason I like Flickr (although there is quite a bit not to like about it too) is that it attracts a lot of traffic. That means I do not have to worry about optimising my site for search engines - which I would need to do if I set up my own photo blog.
But what I have found with Flickr is that if you want a lot of people to visit your site and view / comment on your work, you must link your photos to various Groups on Flickr.
This is a way of "advertising" their presence to people who have an interest in that kind of photo. After all with what must by now be billions of photos on the site it is hard to find any specific person's photos if they dont make their presence known.
Its no big deal to do...when you upload new photos just search to find suitable groups that seem to be related to the types of photos you have loaded then join those groups and link relevant photos
Since I started doing this, over about the past 2 years I have had almost 7,000 hits on my photos, which is not bad although by no means huge given the number of people who use Flickr. Some people get many, many more views. Commenting on other people's work (and signing up other people as "contacts" also seems to attract people to rate yours in return. But I generally do not do much of that. I find I am happy just to put my photos in a few groups and leave it at that.
I have noticed, on this and other forums, that some people seem to object to this kind of approach as self promotion, but my attitude is that if you do not want to promote your work then do not put them on Flickr. Keep them on your PC and look at them yourself.
Personally I do not mind as it gets me feedback - which helps me learn and improve.
