I have had this problem for the last 2 or 3 weeks. Seems to be tied to the adds for the first 5 or 6 posts, if there is an add then there is only room for 1 letter per line. I'm getting it with all browsers (including internet explorer). For a while it was only on the home tab. Going to the Whats new tab would sometimes bypass the problem. No add blocker in use here. Refreshing the page did not help.
