I've seen this a while back when it was still under beta development, but it's been released officially a couple of days ago. Dubbed Blogger In Beta. More features have been introduced to Blogger users such as Video Uploading, Polls and Enclosures.
I'm yet to test any of the new features, but here is a brief description of what the how the new additions might interest you.
1) Video Uploading
Similar to the current image uploading service offered by blogger, users now will be able to upload and insert their uploaded videos of multiple formats to their blogger account. The videos will be saved under MP4 format, and will contain a download link, which means that it will easily be inserted in iPod Videos, the PSP, computers and some phones.
I don't think it needs any explaining, but the new poll offering will be easily inserted as a widget. Since it will be used as widget, this will only work with the newer blogs that have already switched to new blogger layout templates
(if you haven't, do it now).
Very good news to the Podcast or Video-cast people. This new feature will make you able to use your blog as a subscription-feed-based podcast. Which means any video or MP3 you post as a podcast through your blog can be subscribed with on iTunes or any other podcatcher.
This is not the final version of this release, but it's ready for use. To use those new features you have to access your Blog's dashboard through http://draft.blogger.com
, and post from this new address. Tips and further explanations can be found in the developmental blog for the new service.
Now go put them to use.
