Arjun had advised me about it. And based on this it seems lowem has taken a plunge too. But can w.bloggar help in posting the same post to two blogs simultaneously? That would be cool. Let me see if it works. As for w.bloggar, well the GUI is cool. Editing Blogger templates would be simpler here. Also facilities like: having your custom toolbar, spell check and formatting support is good.
PS: It seems simultaneous post (Tools > Post to many blogs) does not work properly, atleast for JRoller and Blogger combination. The post is published successfully on Blogger but not on JRoller, however posting individually works in both cases. Another problem: w.bloggar perhaps does not understand the Blogger Title tag. Also a suggestion: Instead of Blog titles the drop down list of all blog accounts in the toolbar should perhaps show the Blog Alias name.
