Mediacorp's new eBay wannabe, Mocca, doesn't seem to impress me. For many of us who have been buying and selling online a lot within Singapore, we know that the best places to buy goods sold by others are not the generic portals like eBay, Yahoo, and definitely not Mocca--but the niche sites such as:

HardwareZone (for technology)
CozyCot (for girly stuff)
Togoparts (for cycling)
SGSpree (for bluk buying, mostly girls clothes)

Why is that? Community. Large portals without a niche following tend not to have a real community you can identify with and depend on. Sellers are just there to reach the masses and not participate in the community.
