i'm happy to help! I absolutely LOVE this product. I've been a web developer for a few years now, and I've always struggled to find the right cms to get behind. most are in php which I just don't like (ASP.NET all the way baby) and most .net systems are clunky or embarassingly over priced.
I actually intended to make my own, and in fact my senior project was to do this very thing. I wanted to do a lot of the things that this system does, and imagine my surprise when I discovered sitefinity (this was long after I turned in my project tho, so it was a pleasant surprise). I've never found a package that has a more perfect balance of 'built-in' functionality and a customizeability and extensibility.
so now that I've been using sitefinity for about 6 months, I'm happy to share my experience to help others get just as much use of it! as I learn more I'll help more and blog more (by the way my blog actually has three parts
) and be active here as much as I can!
that being said I too am using the live writer and can confirm that it's GREAT. I used it once back in the day for my wordpress blog but since wordpress is so full featured and Live Writer was so beta I ended up ditching it. Now I can use writer to 'fill in the gaps' on a FEW missing features in sitefinity (draft, quick edits, link to flickr) that I'm sure will eventually make their way into sitefinity...
thanks again to telerik for their AWESOME work with this product (not to mention the rad tools!) and I can't wait for the next one!
