Hm! I suppose that's what I've been doing. ^_^ That said, I think I'd still like to put some photos up on my site, in addition to Flickr - maybe more of a scrapbook, keeping Flickr for the notable ones. 'Course, to some extent, I suppose I've already been doing that too, given I use /images/lj there as a convenient, private image host.
Maybe you could just refresh the existing site occasionally, putting up, say, three of your favorites each season, linking back to Flickr, as a means of luring in new viewers to your photography. Flattr
buttons couldn't hurt, either. (I so wish Flickr supported Flattr officially!)
