I've been running out of space on my computer lately, as even with 2tb of storage space, downloading the weekly episodes of ~30 anime results in ~6gb of space taken up every week, and that simply adds up. More after the jump.

Ever since I started downloading anime about 3 years ago, I haven't ever deleted anything. At first it was because I downloaded far more than I could watch, and thus bought additional harddrives to store it all. That resulted in me having loads of space and not needing to delete anything. This then turned into me having a fairly large anime library, and I began to (sadly) fantasize about some day when I would be able to impress people with my library of anime... *pose*... I then bought more and more harddrive space, which only fueled my growing need to amass a large collection.

To this day I've probably watched about 15 series in their entirety. I have over 150 stored on my computer (of course, I have purchased the DVDs of all these shows).
Recently, though, I've been watching current shows, meaning that every week I have ~30 episodes that I download/watch. Not all of these are incredibly amazing omgarchive shows, though. That said, I am still caught up in the whole "hi this is my library of every anime ever created" idea.
This brings me to a decision; do I start deleting the "lackluster" shows after I've watched them, and save only the good ones that I might actually have a chance of wanting to show someone some day... -OR- do I continue to archive everything and buy more and more harddrives to fuel my addiction? To me this is the same thing as amassing a library of books only to throw them out once I've read them.

How about you? Do you watch & delete? Do you keep some? All? Do you burn stuff to DVDs?
