Sometimes there are lots of tweets, pushing the page footer down and creating a big empty space to the left of tweets. Right now I see 15 tweets and it's causing this.
Other times (usually?) the number is less (6 or 7?) and the layout looks somewhat normal.
Unclear what causes the number to change. Reporting in case the 15 is unintentional & caused by a bug.
EDIT: right after posting this I reloaded the front page and it shrunk back down to 5 tweets.
