What I was mentionning was my point of view, not the same as Snowy.
Unless they would be cluttering my whole web browser, like, let's say, that I am obliged to put the page down just to pass the sig, I would find it's a problem.
I don't see a problem with them as they seems alright and in the worst browsers, let's say, in a mobile one, as I mentionned above your posts, there's something in the settings where you can check to don't show sigs and it's as easy as that.
At the worst, you can do so. That's what I'm trying to say. (I know I don't have any problems with my sigs and any others, but I'm just saying that I would not bother turning that option on at the worst case.
Something like my sig is more in width than in height. (678 width x 159 in height) But I guess it's less cluttering than having one which instead in height.
