Well I have been using the Word Press 2.7.1 on both my Sites and it seems that is running great. The GUI Pages that control the setting of your site has been very much improved and easier to use in comparison to the older version. But I don’t see much of speed improvement. Remains to be seen. Another positive point about the Word Press 2.7.1 is the fact that it keeps it’s legacy compatibility with older Blogging tools. I am using the Blogo for mac and it’s working perfectly. Check this App out. I am ordering it.
