I had found WebStarts to be among the most effective free Online website builders, believe me I am a fussy person even to my own likening and will literally spend days to make a site appear and perform precisely the way I want it to be. In a time period from about 6 to 8 months I had gone through a round about every online site builder I could lay my hands on, and most of them have one thing in common. A lot of builders will provide you with easy drag and drop, link building and professional templates, other builders will grant you more apps and options for SEO and so forth. But get this for a whatsoever strange reason, it's difficult to find oneself an online site builder that actually provide everything you need into one builder including the hosting packages and email options. Sometimes you'll find a great builder but the hosting will go for a laugh - get this 1gb space and 10Gb bandwidth, okay wow see this can’t possibly handle a good amount of traffic downloading a free product.
Update : 19 August 2013
I had worked with Webstarts in 2012 and had no problems whatsoever with the platform. However it seems that their upstanding service has deteriorated over the last year. Too many individuals are complaining about the customer service and the functionality of the platform itself, therefore I would not recommend it.
WordPress is the future and more and more individuals are choosing it. I would recommend to download the software for free and host it with a reliable hosting company like Hostgator or Dreamhost - It will work out much cheaper than Webstarts. Alternatively you can use the free Wordpress blogging system.
