Just reading this I would mention a few things.

I'm a programmer application/web, so I would never want my work published elsewhere without permission for a few reasons:

• I should be portraying my work, not someone else uninvolved in the product. This basically leads to misrepresentation.
• Sheer respect of my work was not shown by even acknowledging me. This would make me alot less likely to work with a site. A good majority of yours do not even have authors to contact about bugs and etc.

To be honest, it doesn't really help your site traffic, which is what I assume the attempt is. There are other ways to handle that, I even attempted to contact you(tiny) on curse months ago to help when I see you wanted a site to integrate.

However, maintainence is not worth the effort as you would be needing to go around and update these addons and such to keep them up to date on this site. The biggest misconception people have is the everyone wants a one-stop shop or choice in how they do things, when in reality that's not the key to it all. On a side note the ads are distracting vs the amount of content, so it looks overrun with them.

That said, I would just say for the simplicity of it. It's just poor play to represent anything of someone elses' without simply asking.

Just my two cents.
