OK so all of the stuff I am about to write is heavily OPINIONATED, so bear with me...
I notice that not many people have been leaving comments, and many wonder WHY. Weasyl has an AWESOME LAYOUT, so WHY are things so slow?
The following are a couple theories of mine, concerning this matter:
MOSTLY ARTISTS - Most of the folks here are other artists. Let's face it, many artists are too busy trying to make their work SEEN before they're trying to comment on other peoples' works. Maybe it's because this site started as invite only in its beta stage? Who knows.
HALF FA... HALF DA - Correct me if you can change this... but the top of the pages start a dark blue, then it transitions into the boring "Deviantart grey" that many of us have come to subconsciously avoid. Like DA, Weasyl does not have the "dynamic scrollover preview" that FA has with their recents and favorites -- which would REALLY help, since the THUMBNAILS feature makes this a site littered with HEADSHOTS-- , so maybe THAT is also an issue.
SOME INFO CLUTTERED - I notice that FA and DA have each segment separated into boxes, while Weasyl sorta has a column with sections separated by BIG TEXT. The owner's journal is somewhat lost in the mix.
To be honest, I am wondering if most of the issues are subconscious issues that are associated with the overall look of each page. People get anxious and confused really easily. Gotta make it easy on them, I guess.
Anyway, those were my thoughts.
