Ask HN:Is there good marketplace for selling software beside phone marketplaces

The App Store for Mac is pretty big as is Steam, Microsoft plan to role out an app store for windows as well.

There are also "add-on" stores for big SaaS platforms such as Salesforce.

For mobile apps you can check out Apptopia http://www.apptopia.com/

no just not mobile ....i was asking about more niche market places

as an add-on question... does anyone have experience with selling wordpress plugins? is there a market for commercial plugins, or are most people not willing to pay since there is a lot of free stuff?
