Sure you can; it makes sound, it just says "Internet Explorer". I find a bigger technical inaccuracy in the levels set on the ostermixer itself. It shows Ch.9 as being set higher than Windows, with his blog being somewhere in the middle.
But from what I can tell, he keeps it set around:
Windows 95% (pun intended)
Ch.9 20%
Blog 5%
These volumes are based on his output levels. Recently his blog stream has spiked, but I anticipate it will normalize now that he's finished his X years ago series.
