A Local Shared Object (LSO) is a collection of cookie-like data stored as a file on a user's PC. LSOs are used by all versions of Adobe Flash Player and Version 6 and above of Macromedia's now-obsolete Flash MX Player
I'm assuming this is the LSO mentioned. I heard google made a deal with Adobe to implement search engine friendly flash into their algorithms.
Although I really have no idea about it but I wouldn't think it will affect SEO itself but more of an add-on and a plus if your using flash on your site.
I also believe that Websarga is a bot -
They advertise the services asked in their questions. I think they are using this forum as a means to put relevancy to their links.
Why would they ask generic SEO questions if they advertise SEO? http://websarga.com/whatwedo.html
You gotta give props though- that's one helluva smart BOT!
