If you're simply interested in writing and getting your work out there, then it shouldn't be too hard to find somewhere to post your articles.
However, judging from the list you linked to - I'm guessing you'd like those articles to earn you money too?
That's where things could get a little trickier...
Yes, sites like Hubpages and Fiverr can earn you some cash, but to be honest making a proper living this way is very difficult (not impossible, but still...)
And, if you're interested in providing well-crafted content to other people's sites - you may as well be setting up your own blog/site, and serving some ads on those pages yourself. That makes a lot more sense than revenue-sharing to me.
Blogging for money
Wordpress is probably the most comprehensive blogging platform, but if you're looking for something that's easy to set up, where you can start serving ads very quickly (and without having to copy and paste any javascript) then Googe's Blogspot is also very convenient, and you can link up to Adsense in a couple of clicks too.
Serving affiliate banners on your site is another option, but to be honest none of this is going to make you anywhere near enough money unless you have one thing: TRAFFIC.
How to get traffic to your site
I could write several answers worth of advice about how to drive traffic to your site, but what it boils down to is writing good content that many people are searching for, but not many publishers are providing yet. That's where you're likely to see the biggest gains initially.
Once you've established yourself as an authority, then traffic and money should start flowing a little easier.
Traffic sources
Like I said, web traffic is the key to making money online The more visitors stop by to check out your work, the more money you can potentially make.
Most websites and blogs really on "search traffic" - users searching for information on Google, Bing, or Yahoo - and ending up on one of the sites in these search engines' listings.
There are things you can do to help your site climb these listings (or search engine result pages), but I won't get into that here.
The second major source of traffic for online content is social media. If you set up accounts on Facebook, Twitter, G+ and other networks - and create enough buzz about your articles, people will begin to drop by to see what's going on.
Guest posting and becoming an authority
One major piece of advice I'd suggest you think about before you set out is what topic or niche you are going to cover.
You mentioned HuffPost, but that is a large project supported by a network of people. If you're starting off alone, I'd recommend deciding on one topic and focusing on that first.
Guest posting is something else I'd really recommend. People often agree to guest post (write for other sites for free) because they are allowed to put a back-link pointing to their site.
More than link-juice, guest posting can also give you a chance to showcase a "sample" of your work.
I'd recommend sites like Medium (or Blurtit of course), because they gladly accept public submissions, but also get enough traffic that posting on them is worthwhile.
Finally, establishing yourself as an authority or expert about a certain topic is useful for more things than just netting some ad clicks.
It's also a great way to network and meet people, and hopefully land some paid-work through the contacts you make.
