I consider myself a bitcoin intellectual, and I`m always wondering how can I help the bitcoin economy with my ideas, which I got plenty of. So I was thinking 2 days about why bitcoin (or for that matter other altcoins) is not mainstream yet, and what issues it needs to overcome to be able to grow faster. Some issues that I discovered are practical, while others need the entire community's support in order to work.
So here are the issues I discovered with bitcoin, it's economy, why it is not mainstream yet:
1) Lack of organized promotion campaigns
2) Lack of earning bitcoin methods & bitcoin jobs
3) Lack of a good guide to newbies
4) Lack of a bitcoin "search engine"
5) Lack of a major global financial-economic crisis
6) Lack of a more integrated & united community
7) Lack of social Idols promoting/endorsing/using their influence to help bitcoin
8] Lack of a stable lending system
Nice summary of topics that bitcoin is lacking in order to achieve critical mass.
However most topics are about informing the general public about bitcoin and promoting its use cases.
These topics can be addressed by the community as identified by your list.
However; it will be mainly new businesses who see an opportunity in these bitcoin use cases and who will invest and promote their use case to the general public.
Significant sums of money spent on ongoing promotions over many years is what it will take. Whey else does AMEX, WU and other payment systems continue to spend hundreds of millions yearly. It is a process.
