Off-topic. OnT is On-topic.

Context, context and context.

I'd have to agree with the people who say it's dependent on context. It could easily be used either way and understood/make sense either way as well. I don't think it's too difficult to figure out myself.
I always see it being used as Off topic, right now its 50 /50
to me, OT means off topic. if i wish to go back to topic, i write b2t or simply on topic. meanly because "off topic" is somewhat unpleasant to write.
however, I am still able to to differentiate if someone uses it another way due to context.
I see it more commonly used to mean on-topic - usually after a poster gives a direct response to another poster about a possibly unrelated matter, and then gets back to responding to the OP/the topic - and thus assume that to be the case until it's confirmed.
I personally write it out in full
...actually, I tend to go around that by putting the off-topic/direct-respponse-thingy (often after a quote) at the end of the post.
