I am doing some more work on Blong! over the next few days.
This will add new features including adding your 'last' post to the search results and (fingers crossed) the ability to index all posts from your blogs. I have started working with the Blogger API as of today and should start seeing some results soon.
One of the other things I am trying to work on is fixing the 'No Title' problem. At the moment it simply tries to find the title tag and if you have a custom title (ie Picture etc) it won't load it to the database.
Remember, if you haven't already done so, add your Blog to the Blong! website now and remember to check back regularly for more updates.
