People who don't know anything about Tiny Core read a few lines, and get an impression about it. From this, they either decide to try it, or not to try it. If they don't try it, they never know anymore about it.
I think the comments that Tiny Core is for old computers, for example, has discouraged many people from trying it.
With better wording, people get a better first impression, and more people try it.
I think, if "Old Computers" was removed from "Category" on the Distrowatch site, even more people would try it.
