Most of my sp goes to wearables from my wishlist, so I visit it around once a week or so. I add bunches of stuff to mine intending to look them up later, so I try to weed stuff out at the same time.
I like to think I keep mine fairly well organized. I have plenty of categories, though I don't break down my "wardrobe" section into ALL the subcategories (I have... wigs, face, neck, non-wig head? and that might be it...), and the stuff I keep in Unsorted is stuff that needs to go to more than one place (like if I need an item both for my wardrobe and for a pet's treasure). If I find I've added a bunch of stuff to my wl for whatever reason, I'll go and organize it, but I don't really do it regularly (maybe once a month, idk). I only occasionally delete items, because I'm pretty good at remembering why I put it on my wl. Most of the time, anyway.
I probably sort it about 3-4 times a year. I try to be conscious of adding to the right category if I'm adding in bulk, but it's still a mess. I think I'm on my 3rd unsorted category. (I don't put everything in categories.)
I recently got the filled wardrobe achievement, so I'm sure there are a ton of things that I can remove now.
I do not like my unsorted to get too long so at least once a week if not more. I love Subeta WL! One site I used to play on only let you have a Total of 50 items in your entire wishlist and there were no sections. Subeta WLs are so awesome!
I don't rearrange it often, mostly because I'm pretty good in making sure I have the right category as my default prior to actually adding anything to it, that I don't have to rearrange things out of the unsorted. I also take things as I get them so it's usually pretty up to date too.
My wishlist has been pretty small lately so it is easy to keep it organized :D I think it was several months ago that I really went through it and removed the stuff I realized I didn't need.
Since Lumi started, I organize it daily, since I use my WL generally as a shopping list or as a reminder, or a way of organizing my pets' TCs before I buy the TC space, and I fear that if I leave it all in one category people will gift me stuff that I have already. :bowtie: So whenever I add something, I make sure to put it in the right category. Outside of Lumi, though, I'm really lazy and only update it when I'm in the mood.
I'm not big on adding stuff, but when I do decide to either do that or clear out, it's probably about once a month.
Never too late to win the day

Pretty often, at least once or twice a week. For convenience, my unsorted list is expensive books. I add any high-end book I come across while casually browsing the site so I can keep track of the ones I need. All other items get filtered into catergories. My WL is really a more of my shopping list and I buy from it regularly.
SELL ME FOOD PLS? 🡺 CLICK HERE 🡸I update my WL organizationally once every few months, mine are mainly by price, which is easy enough... But I find that I change my mind about liking things a lot, with the exception of wardrobe items - I NEVER dislike things for my wardrobe! XD
I'm new, so I've been adding lots of things to my list. I've updated it a lot since I joined, mostly whenever I run out of room in the default one...
Did it ~2 weeks ago and now keep it nicely cleaned up all the time xD

I hardly ever organize it... I really should!
