Brucehankins Let's not forget the rankings are based off internal (distrowatch.com) page clicks and really just meant for fun.
Well, I don't pay much attention to Distrowatch, visiting once a year or so for this or that, but the drop in user ratings (not the rankings, which are page hits as you point out) was worth looking at, it seems to me, because folks get information (good or bad, informed or not) from reading them.
Most ratings were 8/9/10. I did a quick read of the "rating = 5 or less" reviews during the last six months, and the main complaints seem to be about the Software Center:
"The big Problem after Installation was, the Software updater always stopped downloading after some Seconds without giving any notice why. Network was not the Cause, so there was no way for me to update the OS."
"Updater is very, very, very slow. Walk away, get coffee, walk the dog, have a shower, go out with your SO for dinner and a movie.. and maybe its done."
"[T]he slow (painfully slow) and clunky (freezes and aborts frequently) package management will make you consider not only other distributions but will frustrate you so much you actually consider going back to Windows."
"Just to update the system, I (most recently) had to restart the process twelve times as downloads would hang and the process abort. Internet connection is fine, other distributions are fine. The problem is Solus."
Not surprising, and the complaints align with Smith's review and what we all know already.
