I've found that over the course of a few weeks, I've gotten used to the avatar alignment. It becomes easier for me to read the name quickly and recognize that, or use peripheral vision to see the avatar.
As for the space between posts, yes, I see what you mean. I can fiddle with the spacing to see if there's a good balance.
We've upgraded servers, so things should be faster.
As for "too blue," well, I'm not quite sure what I can do about that. It wouldn't be too difficult to create a style of a different color, if you have a suggestion for one.
