Miniaturized Threads?

[expavr]

Why do some threads appear on my iPad in a miniaturized format? For example the thread on suicide doors takes up less than 1/2 the width of my iPad and is only readable if I expand the words using the iPad to expand the wording. All the rest of today's threads are full width and readable with no adjustment on the iPad. It seems like this condition has been popping up more often lately. Anyone else seeing the same thing?
