I marathonned SG1 from S1 to S3, watched S5 and S6 on the Original Squintyvision (30Mb downloads!), then started drifting at the start of S7. Got back in for a few eps in the middle, then drifted out again. Watched Gemini plus the last 5 eps of S8, and other than that, only The Pegasus Project, The Ripple Effect, and 200.

So, yes, I suppose you could say that I've been slightly sporadic about SG-1 of late. I do the same for BSG and Torchwood. The only show that inspires me to omg, get next episode QUICK is Heroes.
