We do, apparently.
Siglines have been a standard here at DailyKos for many years now.
I posted my very first Sigline diary so far back that we (or at least I) called them Taglines way back then.
I've posted a few more since then. Other Kossacks have also posted Sigline diaries, but not for a while.
I've been meaning to post this thing for years now. Hope you like it.
Join me below the Fleur-de-kos to see if you find your Sigline amongst them...
