This is a snippet of a conversation with swedishbadgergirl and I found that as the conversation got bigger (upwards of like 30 messages total) this happened. I've seen this happen with a couple of posts too, and I was thinking that it would be interesting to push the circle dot (which is next to the post) all the way to the left, like it is with the one up in the left corner, next to your /u/ (or nick or handle what have you). I mean maybe this is just a problem for me (1600X900 resolution) but it gets to the point where a conversation gets unreadable. I think I mentioned this to insomniasexx and finally got around to posting the screen cap... Anyway the text near the "end" of the conversation/s looks like this:
T
Y
P
E
D
and it makes the post/s harder and harder to read. I think even the PMs should have all text pushed back to the left most side and continue like that.
