My activity rates and productivity are, have been, and probably always will be, fluctuating like crazy. The reason is simple: i'm temperamental when it comes to computers. If you put me in front of a laptop, especially with one that has a keyboard I dislike, and a laptop that I'm used to being kicked (figuratively) off of, my productivity and relaxation will plummet. Outside things can also effect me, such as the amount of fighting in the house (If there is a large amount of conflict in the house, my writing goes up in productivity, but I might be inactive on most other things, although this depends on my reaction to conflict. If I feel annoyed, expect a dozen angsty stories, if I feel depressed a bit, expect me to do nothing but lurking on blogs and chatrooms).
Windows types will also effect me greatly: I am used to XP and 2003, and the setup of Windows 7 makes me feel quite uncomfortable. BZp's skin is also a contributing factor, as it too makes me feel a little out of place.
