Will a professional programmer lose anything if he doesn’t learn object oriented programming?
Yes. OOP is a very important programming concept—a professional programmer who is not familiar with it will be unable to understand vast swathes of high quality existing code and will have a great deal of trouble passing interviews or contributing effectively at great companies.

Why do so many London based SAAS startups only price in dollars?
UK customers are used to paying for some things in dollars. US customers are likely to be very uncomfortable paying for something in a foreign currency. So if you are only going to support one currency at first, it makes sense to pick dollars.
[... 62 words]Which online platform can you recommend for organizing group trips? I’ve review startups that tried to build that, but failed a lot. Anything you can recommend that you used or use continuously?

Is it worth it to give up equity in a seed stage company for something other than money? E.g. access to multiple consultants/mentors, as well as regional angel and vc groups?

[... 75 words]What are some tips for a successful Ignite talk?
Practice. All public speaking can be improved by repetitive practice, but this is especially important for ignite talks. The one-slide-every-15-seconds format is extremely unforgiving—if you haven’t nailed it, in private, speaking out loud at a sensible pace there’s no chance you’ll be able to keep up with the slides when you are on stage.

I don’t think there’s an official policy on this, but I think I’ve heard of it happening so I imagine it’s handled on a case-by-case basis. You should talk to YC about your situation ASAP.
[... 49 words]Can top VCs hire almost any employee they want for their portfolio companies?
There’s little a VC can do to convince someone to go and work for one of their portfolio companies that the company couldn’t do itself. They might hear about good candidates through their networks, but that candidate will still have plenty of other opportunities to chose from.

[... 64 words]Is there a website or app that helps you track what you have completed each day?
I’ve tried a few solutions for this. Surprisingly the one that has stuck for me is Evernote—I keep a different document for each week (I tried a document per day but that was annoying to update, and meant I didn’t look at my older notes as often) and each day I add a new header at the top of the document for that day. Being able to link through to other notes from my day summaries is useful too.

[... 71 words]How can I invest in pre-IPO companies like Quora, Github, etc?
Get to know the founders and investors and see if you can get involved in a future funding round. If you don’t have at least a few hundred thousand dollars to invest you probably won’t get very far though, an even if you do you’d better have more than just money to bring to the table—these rounds are often over-subscribed which means the company can pick the very best out of a number of investors.

Do you have any programming side-projects? If not, I suggest starting one. You’ll learn a bunch, it will impress interviewers (and help you pull ahead of other candidates) and it will help you build confidence in your own skills.
[... 83 words]How can I find info on startup companies in stealth mode in a particular market segment before they launch?
The whole point of stealth mode is to prevent you from doing this. That said, if you make sure you’re well connected with entrepreneurs and investors in that particular space you’ll increase your chances of hearing about things before they launch.
