There is a certain knack to using websites to generate traffic, it is having something in common with lots of other people. It seems the more you have in common with lots of other people the more people like/repin/whatever your stuff. This is easy enough if you are into, things that the 'swinish multitude' [quote from Thomas Burke] are into like fashion or fitness or fast cars or motorbikes. But if like me you think these things are vapid, turgid and quite pointless it is almost impossible to realistically pretend that you do.
So, not really getting sites like pinterest, I recently stumbled across a method that works, and it is the same as above, kind of. My pinterest account had lain dormant for more than a year, the odd addition here or there, but it never did much and it had little going for it, then bored on a Saturday night I started pinning a little fetish of mine, cute chicks who wear glasses, I was in effect perving it up. Nothing gratuitous of course, [there might be kids out there] just pleasant to my sensibilities.
Now, I can hear your tiny minds fumbling in the dark, grasping out that you are just sharing with like minded pervs pictures of other things to perv about, but you are only looking at the tiny part of the venn diagram that I was looking at in the first pervy place. Since I was only looking at this one part [and since I am largely ignorant of such things] other people see the things I cannot. You see 'cute chicks with glasses' also exist within a large range of other subsets of which I don't care. Among them tattoos, celebrities, models, they have allegedly fashionable hairstyles, some wear allegedly stylish clothes, and of course some people think they are nerds or geeks. So I get repinned not only from weirdos like me, I get repins from people who have fetishes I completely do not get and cannot see.
This method for succes is not just for pinterest, there are several other similar sites out there which are more nuanced, from imgfave which can be a bit more explicit to gentlemint which is for blokes [though I do not know how they can tell from unless it is obvious from your e-mail and you do girly things], there is even a british version of pinterest called pinspire. These sites of course do not have the same number of users as pinterest, but as they are more nuanced there is a better chance of people coming across your stuff and doing the equivalent of repinning, smaller ponds etc.
There is a place for everyone in this weird little world, even for us pervs, but it does takes time. I am considering opening two new boards on pinterest now, one for short-haired girls the other for redheads, there is much scope for cross perving here.
