One of the people testing Finch reported a problem using it for his weblog on weblogs.asp.net (the original .Text website). I have looked into this and it seems that they have removed two of the SOAP webservices that are shipped with .Text. Finch uses all three of them, BlogContent.asmx for retrieving the last x postings, SimpleBlogService.asmx for most of the inserting and editing and ASPNetWebLog.asmx for deleting (which seems like a simple eature to me, but is not included in the simple service).
On weblogs.asp.net, for some reason, only the simple service can be reached. Maybe, I should focus on implementing the MetaBlog API, which is also implemented by .Text (and many other engines), but does not use SOAP. XML-RPC is fairly simple to implement, but it will take some effort.
I will keep you posted.
