(This article's critique of BSPs does not include BlogBus.)
Since you dare to call yourselves professional BSPs, why don't you have the guts? You operate in a sneaky and insincere manner. Most of you use the same MuBlogSystem, tweaking it a little before putting it out there for business (this is the blogging system that updates all diary pages every time the template changes), and your operations are dismal. Yet you want to benefit from portalization. Who would want to use such half-human, half-demon BSPs? Poor server quality, terrible and bizarre customer service attitudes, extremely ugly ads everywhere, unstable systems, and problems cropping up one after another.
Sigh, what I've said so far is completely disorganized. Let me go through them one by one below.
