Gravitar's are an image you use, Like your Betty Boop to help you define yourself or your site.
First, I love the name ventamatic. The name is an open invitation. It works.
Here's a tip after taking a second look at your site. It's kind of how imaging happens.
1. Your site is an extension of part or all of you. I'm in the 8th week. The first 3 weeks I focused on the writing style, the flavor if you will.for me I wanted get some humor into it. You might feel differently about humor and that's okay too.
2. Consider what "ventamatic" conjures or evokes in your mind. To me it's an invitation to share gripes. Jack Black on steriods. You might have a different idea and that's okay.
3. Your imagery, the sunflower, looking inward and your question, "Do you remember being held as a baby?" doesn't exactly invoke venting. Plus these are big questions. Deep stuff.
to me, your imagery, from Betty Boop to the sunflower and the question don't invite me to vent or participate.The question does but no I don't remember, so what I did I do? Moved on. Then I saw the sunflower and I thought,"Well hope you enjoy the view." and I looked for something else.
Deep stuff involving big questions will get a niche following. If that's what you're looking for you're doing fine. It has an eclectic kind of appeal working.
3.b. Have you ever been in a long line inside a bank and just when it's your turn two tellers go on break? Ventamatic is a Rodney Dangerfield bit titled, "Did I ever tell ya I don't get any respect..."
Don't be afraid to ask the small questions that maybe a wider following can more readily relate. If you want a wider following.
From a purely marketing/communication perspective IMO, "ventamatic' is the strongest part of your website. Holy jumpin' it just screams, tell me about it. It's an invitation!!! It's a welcome mat! Frankly, it's brilliant.
I would suggest you focus on ventamatic as an invitation and your execution can be anything from the agonizingly confounding such as looking inward at a sunflower and/or coping with a frustratingly bad hair day.
That's my 2 cents. Hope you find some value and use there.
