Imagine your blog is like the front door to your house. When the door is opened we expect to see a smiling face welcoming us in or at least willing to accommodate our query.
Now imagine that the front door is never opened and instead you talk to a voice through an intercom. From the tonal range you can guess whether the person on the other end is male or female but we're not given any clues as to their age, height, body language or facial features.
It has a similar feeling as talking to the priest in a confessional booth. Impersonal. Not relational.
When you're talking through an intercom your mind is trying hard to assemble a jigsaw picture of who you're talking to. And your mind can make some pretty large assumptions which are more often than not, completely devoid of the true picture.
I'm not sure about you, but I struggle to get past this barrier. If I stumble upon a blog that has no picture of the author I'm less likely to stay and strike up a conversation. I like to see who I'm talking to and being able to see a 'face' gives me some reassurance that a person is behind the content and not some automated process.
Furthermore, a picture on your blog can add a high level of branding. Why? Because in the blogging world - YOU are the brand.
How often in comments do you see a picture of someone and instantly recognise them as the author of [insert bog name here]? And, if you consistently see a picture turn up it will intrigue you to search out who this person is and what they're on about.
Photos of 'real' people is what propels social marketing tools like MyBlogLog because we crave connection with another human being.
On the flipside, if you don't have a photo of yourself on your blog, you're allowing your readers to make their own assumptions which in most cases won't be great. You become an 'intercom blog' that forces people to make their picture of you and often this will come out terribly wrong.
Do you agree? Or, do you think it doesn't matter if blogs have pictures or not? Do you have a picture on your blog and if so, why? If not, why not and do you plan to add one anytime soon?
I'd love to hear to your thoughts...
