As another EPZ member rightly points out, if you compare photos in the Gallery with blog posts, the blog posts seem to get more attention.
I'd go even further and say that they seem to get a disproportionate amount of attention, in comparison with gallery photos, that is. Unless you're one of those brilliant photographers with a big fan base on here, in which case I suppose you have nothing to complain about in terms of the numbers of views on your portfolio photos.
But for those who don't shine in that department, but do publish blog posts, it's indeed a lot easier to get attention for their writings and their blog photos than for their gallery/portfolio pictures.
Why? Are we such brilliant writers? I may have to disappoint my fellow blogger, but I don't think that's it.
I think it's much simpler than that: there are relatively few bloggers on ePhotozine, so each blog post can get quite a bit of attention. It really doesn't take that much to get more than a hundred views on a blog post, and that's a lot more than my gallery photos get on average.
Is this an important consideration? No. I just like writing and sharing stuff, and I'd still do it if I only got five or ten views.
An acquaintance of mine recently suggested that users of social media and blogs are exhibitionists at heart and like getting attention. I don't agree with that. I just like writing and sharing, and writing to me seems to make a lot more sense when it has a purpose, when I'm writing something for someone to read, rather than just for myself.
I'll leave the philosophising about blogging at that. It may be a bit much anyway for the average reader on a Saturday morning, so let's not make this too long...
