maybe i'm wrong, but it looks handwritten, not a font

I've seen it used on different blogs (http://frufly.blogspot.com and www.joridkvam.com), so I think it's a font

you mean on the images at the bottom of this blog ?

all letters which are supposed to be the same are different.
Maybe it's a font with alternates, bu i don't think so

on the other blog i don't see something that could be similar, please provide us images

Nothing like it on joridkvam. The font on frufly.blogspot is different from your (handwritten) sample. There is only one common letter, the n, but these are not the same.

but now I'm thinking it could be one of those where each letter is a word (lousy explanation, I know..), like many of those found here http://kevinandamanda.com/fonts/fontsforpeas/

The one on frufly.blogspot is the Mrs Blackfort.
Try thank you and you will be shocked thinking is is the same as your sample.
The one on http://www.joridkvam.com/2010/07/good-start.html is also handwritten and again completely different from your (handwritten) sample.

Are you one of those who think 'I see it on a screen, thus it is a font'?

yep, you got me, sunshine!

The links between the letters is perfect but cever in the same point (vertical position). It's not a font.
Or, if it's a font, it was handly modified with a graphical software (but I don't thing so).
