I was a big (cheap) fountain pen collector for a while and used them almost exclusively in school, but then I had a few jobs that didn't involve much writing and they kind of fell by the wayside. I'm still discovering pens that I left full of ink and after a few years they can really get messed up. The cheaper ones end up with nibs broken from rust, but the ones that avoid that fate get their feeds and filling systems clogged up with dry ink instead.
Now I try to have only two or three pens inked at a time because I'll forget about any more than that. I had myself a little flush-and-dry party the other night because I discovered several that I had left inked.
I can also definitely second the recommendation for a stub nib. I ground a custom one at one point and it was just perfect, nice line variation and smooth writing.
