When people ask for forums specifically about buying and selling websites I send them here. I don't know why you get the sense that I'm out to only make money and provide as little help as possible to everyone. I want people to succeed and all of the software tools I've built are as a result of something I'm annoyed with. i.e. I've made tens of thousands of dollars as an Amazon affiliate and roughly a year ago I was fed up with how slow it was to create affiliate links in Amazon so I commissioned a local Wordpress developer to create a plugin to help make this process faster and the end result was: EasyAzon.com
Then because I value my time and money invested at greater than $0 per hour I charged for it and now after several iterations and free upgrades for customers we're sitting at v2.0.4 of EasyAzon.
Now getting back to Site Finder Pro I created version 1 of the tool because I wanted a starting point to help speed up the research process for websites and utilizing the data source from Flippa seemed like a good natural fit for the beginning.
Yes you could go to the website being listed and see more details about the site etc. but the point of this tool is to be able to look at a lot of listings faster and when something catches your eye, press the button to expand more results and then the tool goes out and looks to see how the site makes money, where it gets links from (a few key spots like Dmoz, Yahoo Dir, BOTW) etc. as seen here: http://screencast.com/t/pCyM0ATXp
I should again clarify that I don't just release software and never improve it. Going back to the EasyAzon plugin as an example (because it's the oldest) I have done 3 major upgrades and about a dozen minor upgrades and users got free updates to each one.
In any case, I'll be back to reply in this thread but I'm not that quick because I frankly try to steer clear of spending too much time on forums because I want to spend more time working and less time talking about the work I should be doing.
i.e. I'm launching a forum on one of my really high traffic website acquisitions this week. Got two sponsors to provide a ton of free products related to the niche in exchange for exposure during the forum launch. Done this method of forum launching (again outside the marketing niche of course) twice before with great effect and this will be the third time I've done it.
