I dont click download links until I understand what the product is. It's disappointing to spend time learning about a product and THEN finding out I can't use it. It should be front and center, or have a logo big enough that a quick full length page scroll will show at an instant the platforms available without having to read.

https://obsproject.com/ clearly shows it is cross platform.

https://adium.im/about/ clearly shows that it is not.

I almost wonder if shortsighted optimization of the sales funnel encourages not putting the platform up front since that would drive people away (who wouldn't buy the app anyways, but that's not always apparent).

Either way it didn't cost the website owner much to lead on some people not in their target audience.

I disagree. There are a lot of sites out there that detect your OS and only show you downloads appropriate for your platform.

You are right but it's likely most people wasted a few minutes reading about it before discovering this?

Ah, the price of Running Ubuntu/OSX/Windows....it always bites you in the ass.

This is like the B2B SaaS marketspace - it's almost taken for granted that your app integrates with Salesforce. People are surprised if it isn't.

However, anyone who runs, Microsoft CRM, SugarCRM, Netsuite, etc. - are all used to hearing "Sorry, we don't integrate with X". I'd say ubuntu falls into a similar category....
