I've gathered a few sites that, well might make you feel a bit like a Peeping Tom. However, these sites are very powerful in their very personal, intimate, yet anonymous content.
First, is PostSecret. It's a blog that's been around for quite some time, however I'm surprised to often find people that have never heard of it.
"PostSecret is an ongoing community art project where people mail in their secrets anonymously on one side of a postcard."
Many postcards from the site are extremely personal (in an important yet uncomfortable way) and I think I'll just re-post a rather sweet one from the blog:
Next, is Missed Connections. Here's a quote from the blog:
"Messages in bottles, smoke signals, letters written in the sand; the
modern equivalents are the funny, sad, beautiful, hopeful, hopeless,
poetic posts on Missed Connections websites. Every day hundreds of
strangers reach out to other strangers on the strength of a glance, a
smile or a blue hat. Their messages have the lifespan of a butterfly.
I'm trying to pin a few of them down."
And, an example:
The reproduction print is available in Sophie Blackall's Etsy shop (as well as originals if you're lucky to snag one).
Lastly, is from Ginger Anyhow with Embroidered Text Messages. I love this!
These sites offer some content to contrast against my (and maybe your) purely decorative (and I love decorative as well) blog-surfing.
