it surely does, how people can invest in a such useless app, well there is market for everything, but this is insane, well not as insane 16 billion whatsapp valuation, the market is crazy, CRAZY!!!
it looks good, but one recommendation: the call to action button that is in homepage ("Contact Us") that is color green, change it to maybe an orange color or a complementary one. The same in http://www.sprypoint.com/pricing. Just my two cents :)
We follow a "Marvel" scheme, for example: one server named ironman (background processing), another capt-america (sessions) and finally thor (storage) and so on, but follow any that is usable and meaningful for your team
Its not bad, is really nice, but Git has one problem, when you codebase is big, the process takes a long time, imagine git scanning those 8GB every time you do a commit, that is why Facebook was looking to port all their code to another VCS
one thing you should wonder, do you think is good enough to leave a image to represent a heading? you might think, oh cool that look nice, but remember it affects SEO, there is another solutions for this workaround (cufon) but is not as flexible as webfonts, i think that webfonts will never replace a system font, but the web designers need to get a fallback, a reliable fallback.
Answering your question, i think is not possible to get the benefits from a webfont, but one possible solution for your problem related to the downsides is to ask the visitor to install the font required, but it would be not practical.
I'd like to say something, stick to PHP. PHP is a very neat programming language; I recommend you to read about Composer and PSR standards, but if you want to learn something different, try with Python or Ruby, both languages are kind of similar, hope it helps.
I would recommend you to use PouchDB, its a similar approach, but in this case you use CouchDB as a database, it can be used offline and it syncs http://pouchdb.com/
