While I too am just starting to piece together all of the tools & resources that'll help build traffic, I've found 12 or 13 sites that let you build your own website and offer free web-hosting. Naturally, they limit you to all the features... as they are hopeful you'll upgrade to paid hosting (Which on most I don't necessarily recommend). But many offer a affiliate partnership as well.
Although, I'm falling asleep... I'll name a few (SQUIDOO was already mentioned) but there's..
~Weebly
~Jimdo
~Yola
~Synthasite
~HubPages
~Tumblr
Naturally, the topic is getting traffic, so this is kinda a split between the two, as Hubpages for example has a high flow-through rate and you can build popularity, while some of the others it's more like "practice" for building better looking sites, and again requires some effort to build traffic as mentioned above.
Also, if you have a blog with the Big "G" on Blogger, there's a fella that will have you in his trance when you see all he has to offer regarding blog tips, tricks, tweaks, and hacks, if you really want to start understanding how to use web tools, and his work is so simplified it's awesome. I've spent endless hours and learned everything from writing link codes to tweaking the CSS template codes to add columns, navbars, etc... But he also lists every blog registry, and search engine you can imagine, for optomizing your sites recognition in search and gaining traffic.
Much like Linda here, and several others who give quality information on several subjects concerning marketing, and getting started, this site is in my opinion like 5 Star; a must have...

Tricks for New Bloggers
Hopefully, I didn't overwhelm anyone, as I am still trying to get my sites looking better, and have better content before attracting too much traffic. After that, it's on to learn keywords, backlinking,
SEO, and my personal handicap; organizing it all to harmoniously flow together!
I hope that helps.
As for me Good-Night, well actually, Good Morning
