While I love getting comments, I wouldn't let the unusefulness to others or a prospective lack of comments take the fun out of iconning. There's a short US/Canadian show from 20 years ago that's pretty unknown in North America (but somewhat beloved in Germany, judging by the reruns) called Three for which I've made icons.

*sigh* You're reminding me again how much I miss the community of fandoms. Why did they all have to move elsewhere?
