    This is an archive of the PowerBlog blogging desktop software application. PowerBlog is no longer supported as of 2005 and stopped working when incompatibilities came with .NET Framework v2 and Internet Explorer (which was used for WYSIWYG HTML editing). PowerBlog was a powerful and intuitive Windows desktop blogging application. One could post blog entries to an XML-RPC/Blogger API host, FTP host, or other host. It was extensible using .NET assemblies or by using VBScript/JScript scripts. It had an Outlook-style article browsing interface. PowerBlog's closest competitor was w.Bloggar until Microsoft Live Writer was released, which made PowerBlog an irrelevant product. If you are curious about PowerBlog's author and what he is up to, visit http://www.jondavis.net/techblog Feel free to send Jon a message at jon -AT- jondavis-dot-net (<< anti-spam) asking him what he's been up to with blogging solutions lately.
