Facebook has been making a few changes to the way your newsfeed operates, some of which have been very visible. But it's also made one change that you may have not even noticed, and might not want.

The visible changes are nice. For one, clicking on a picture now opens a pop-up rather than taking you to the page with that photo: nice for those like me annoyed they "lose their spot" and have to rescroll through previously read updates. Another is changes to the fan page design, which now mirror the look of profiles and gives Facebook a uniform design throughout.

Okay, nothing wrong with those tweaks. However if you're like me, and comment on your friend's statuses and prefer to just watch others, you may have noticed some people apparently are commenting much more, and others much less. This is due to a change in how the site displays your newsfeed: if you haven't commented, liked, or looked at a person's profile regularly, they have now seemingly disappeared.
