I joined Fluther on my iPhone. How do I get the icon or widget on my home page?

See http://www.fluther.com/blog/index.php/2008/01/16/add-fluther-to-your-iphone/

Press the plus button at the bottom of Safari. Click ‘Add to Home’. Needs firmware 1.1.3

thanks this site is great my question was answered correctly almost instantly

Also, you can use a site like Launchrz to keep all your webapps separate from the installed apps on your phone. It lets you have a Launchrz page of all the webapps that you find interesting and it behaves like the home screen. I do both, I keep a launchrz page with all the webapps that I like and then also put webclip icons on my home screen for the couple that I found there that I use frequently (Newsgator, FlickIM, Hahlo)
