I use icons to express my interests, so having a wide variety of icons means that I get to show a lot of different sides of myself. I also use them to show certain moods, as a way of displaying how I'm feeling - for example, on a day I'm feeling cranky I'll use a sassy icon. And, some icons are really pretty, so I like being able to show them off, even if I didn't make them. Of course, icons are definitely more of a want than a need, but they've been strongly tied to my LJ experience both in different fandoms and as a graphics maker, so I'm quite attached to having a large variety of them. Does that make sense?

Edited for grammar.
