"Bubbles" a poor choice for technical issues
An example (I hope) shows why this is true better than anything I could say:
Software Update crashes? What to do?
On the plus side, the new format doesn't mangle crash reports by interpreting crash text formatting as html tags, so that much is a step in the right direction.
However, the fixed size, narrow bubbles mean the readability of almost any long lines of text pasted into a post user content will be greatly diminished. If this was just a chat site & all the posts user content we read were normal text paragraphs, all the soft line breaks would not be so much of a problem. But this is a site purposed for technical discussions, not social chit-chat. Or at least it used to be.
Please give this some thought & provide some way (automatic or otherwise) to relax the formatting so where appropriate we can expand content into the otherwise wasted white space to the left & right of the page.
