Here are some "nice finds" I did over the last couple of days:
Ning, a social web service, let's you create and customise applications such as voting sites, online groups etc... They have just announced a new template which allows you to create your own YouTube site. By using a template you can create your own branded video upload site, including the social side of things like rating, commenting and the embedding of clips on your own blog or site.
I can see how to use this; creating a YouTube copy for just interviews with leading bloggers or one with video tutorials on new media. I made a quick copy and loaded up an example video so you can see what I mean.
Next is a new RSS to e-mail service called SimplyHeadlines. I think this is a nice one for people who want to stay up to date with news headlines by e-mail based on RSS feeds. The lay out is very easy to read and they also have a "mobile" version for Blackberry or other mobile readers. Another one to add to the list of "RSS by e-mail" readers.
And then there's the mix of blogs and forums set off by Tooum and called Switchboard. Their hosted service includes categories, tagging, RSS feeds, sticky posts etc... Combining a blog and a forum can definitely have its value in the context of community creation. The "blogforum" is quickly set up and very user friendly. I tested one here.
