Well I like it, so how about you do what your name says?

hey Zvi.
 
I had similar debates when I put together my portfolio which includes some reels / video walkthrough's. I wanted an elegant embedding solution that would be professional and fit well within my site framework visually as well as work across all devices (iOS particularly).
 
Both Youtube and Vimeo do it well. I decided in the end to go with Vimeo (with plus membership). Firstly, the quality was slightly better on Vimeo for many of the tests I did. I tried different compression settings in MeGui for various video gaming and snowboarding videos and Vimeo came out slightly better. I put this down to Vimeo plus's 2 pass encoding they do rather than youtube's 1 pass.
 
Also, Having a plus account lets you fully customize the embed's visual style and the elements that the user can see, as well as forcing 'HD' for desktop users if you feel the video deserves it. You can also remove the Vimeo logo and change the colours of the controls to make it feel part of your site. Example: http://www.webdale.co.uk/work/portfolio-2012/
 
In the end it felt like Vimeo's focus is on video professionals and creatives rather than the more social and 'for the masses' Youtube. If you're after more organic views and more comments / social interaction then perhaps youtube is the right way - but the kind of people you'll get looking and commenting will most likely be very different to those on Vimeo.
 
Your video embeds will display fine on all devices, the iframe deals with all that.

Your not uploading, only embeding.
Simply add the video pages URL when you're writing the post (if your in HTML writing mode) and it'll do the rest.

Here you go...

Unless you pick up some good contracts when the time comes, the experience you'd gain working for someone would be invaluable.
 
Keep up to date with the latest practices and coding techniques, be passionate about what you do and develop your skill set. Work hard on what you enjoy.
 
Sure, go to uni. Enjoy it and do a relevant course but I suggest you take a job for a few years.
 
You'll learn how to deal with a number of clients, code to a high standard, learn how the business is ran all without the wonder of where your next paycheck is coming from.
 
When you're working there, take time to take a huge interest in how it's run. From winning contracts to signing of projects. Understand the work flow, the finance, invoicing etc etc.
 
Whilst working for them, start to pick up jobs on the side. Do some marketing, get a website together and get your name out there. Get everything in order, stick to a good work flow and get used to dealing with clients without the protection of your employer.
 
It's hard work and far away from an easy life. A job has security and a good routine. Freelancing and being self employed, you spend a lot of time running a business. Meetings with clients, accounting, marketing, networking etc

I'm afraid I can't give you any advice as to what it's like to be a freelance web designer, as it's a path I'm only just starting down myself, and then only part time as I build up a portfolio and hunt for some customers. However, seeing you are only 14, my advice to you would be to make sure you do well at school, keep following your dream and take every opportunity that comes your way to gain experience. I don't know what the professionals would say, but I'm sure getting further relevant qualifications after school could only be a good thing, and would stand you in good stead in the future if you decide that freelancing isn't right for you. And any way, college/university is good fun, provided you work hard too that is I would also suggest that gaining experience with a reputable design company prior to going freelance would be a good idea. You would learn so much just by being with professional people on a day to day basis.
 
Being a freelance anything is hard work. It's not just about 'doing the job'. You have to consider all the financial aspects of being your own boss. Finding customers, bidding for work, tax returns, invoices, chasing up payments etc etc. This is not to put you off becoming a freelance designer, because I don't know many 14 yr olds who know what they want to do with their lives, and that is admirable on your part. All the best to you.

Yup, usually achieved using AJAX and the onkeyup event.
 
I have never used this, but it looks promising (and free): http://www.geobytes.com/free-ajax-cities-jsonp-api.htm
