Why Don’t You Comment @Mashable?

Mashable is of the most popular social network news blog and they got me thinking today. Looking through their new design they implemented few weeks ago I noticed that even before redesign they had really low commenting just as I do, even though they are very recognizable by providing awesome Mashable Party where many tech people get together and just party their ass off, unlike other parties where they just talk straight business!.

Anyways my point here is that I wonder why Mashable does not receive as much comments as other Tech blogs do? Like for example

TechCrunch, Scobleizer, Read Write Web, GigaOm, Gizmodo etc… even though their traffic is booming, their twitter reached over 12K followers and 174K feedburners!

Am I going to face same situation in next year or two?

I want to know why people do not comment on certain blogs? Even though topics are almost identical

TechCrunch:Here =41 Comments

Mashable Here =2 comments
