I have been a user of Wikipedia for a long time. But have rarely been editing.
My perfectionist personality is actually the main reason I don't edit articles often here. I write long when I do write and because of wide range of things that I have read in life and specially because of my relatively eventful life it is hard for me to find sources of my knowledge and create a proper article.
Most of the time even in discussion pages I just read rather than write and sometimes I discuss while forgotten to login. So in fact I am really way more active that I look so.
I think this is more than what you wanted to know about me anyway!
