 :::It's not that, it's that your signature starts on a new line, lead by four colons (20 spaces).  Standard communication on talk pages means one extra colon for each reply, adding five spaces, to allow for easier reading.  Extra spaces and lines are usually used to indicate new types of discussions, quotations, extracts, and general breaks in the flow of the conversation.  Your signature, though very distinct, I'm sure that's why you choose to include it the way you do, really makes reading talk pages more confusing, at least for me.  Spaces like that threaded through the text makes it look like a series of interrupted replies, out-of-order responses, breaks for individual comments, etc.  It makes it harder to parse the page.  If no-one else has ever mentioned it, perhaps it's just me.  Or, your contrib count is around 1K, it's possible that not too many regulars have seen it.     Wikipedia's rules:simple/complex
