Erm... while in my own case, not signing is due to hitting return when I runout of space ratherthan carrying on typing (I learnt my keyboard skills on a manual typewriter), I would say that while I abhor unsigned negative rep ..... I think people are entitled to leave positive unsigned rep..... I mean, occasionally I might do it if I rep someone who has coincidentally just repped me and I don't want it to look like a quid pro quo.... but generally I sign or PM if I realise my mistake...
