Literally any name can pique my interest. It doesn't always have to be an unusual name to make me interested in working on it. When last time I watched a Batman movie, I saw a common surname in the credits and just... felt like working on it for the same reason you mention. Some days I feel like working on surnames that haven't been added on WikiTree yet, other days I'll work on common names, and still other days I'll pick a random one I either like and have heard of, or looks complicated to spell.
The reasons why I pick all of them on a whim, besides the reason I just do better doing whatever I feel like working on whenever: I like including everyone. It partly stems from childhood, often feeling left out, forgotten, teased, or bullied (ironically, not due to my own name. If it did ever happen, I don't remember, and nobody probably did because it sounds too close to a bad cussword, and kids would have gotten in deep, deep trouble for it), so my own experienced heightened my empathy for others. In this case, putting myself in others' shoes. On one hand, you have less common names that have the least people working on them. On the other hand, those whose families have common names need all the help they can get, drowning in the great sea of that one name that so many share, yet so many aren't even related to each other. This is because many were given the surname after generations of a profession being carried down through a family, or simply from being called something like John the Smith shortly before surnames came about.
Speaking of which, I did try working on some Smith's since I have a friend who doesn't hardly know anything about his lineage. I ran into a frustrating brick wall, however, so I had to take a break from it. Lately, I've been working on Cooper's in my close family, branches I had missed when I was new on WikiTree. I'm eager to find record of one being recorded as a barrel maker/repairer (cooper). It was once a very important profession, just as smiths were. So far, just farmers and a pastor, though.
Thank you for noting this reminder to others, though! When I get more time (currently helping a family member recover from a surgery), maybe I'll swing through some random Winn's, if I remember. ...Ah! I know! I'll do a few older ones, dating back to the 1500s. Looking back in my list of contributions and seeing them will make a good reminder.
This Winn's record (not much to go on, yet at least) contains an image of beautiful handwriting in a parish book: [[Winn-3516|Framers Winn (-abt.1588)]]
Gotta love old handwriting.
