I've heard from a reliable source that the search engine used here (relying mostly on the tags) will not be improved soon. I don't not much about software or programming, but as a user of the internet I know that search engines which react to words in texts and documents (tags are an additional help) are not a novelty. This and some other (probably needed) improvements won't happen soon. Corporations and politicians (those selfish and ego-centric creatures) are supposed to make bigger steps than to improve a search engine - they should even voluntarily lose profit if they wanted to make their activities more sustainable and eco-friendly.
What shall I do in the meantime? I shall post content and comments and contribute to discussions. Also, I shall post here exclusively if any my scientific paper is accepted. With enough my material, I shall be increasingly posting more of my raw thoughts in content and pages about renewable energy (I first want to check whether there is some quality in my writings or not). All I need is this meshwork working by the year 2020 (and maybe later). Time is on my (our) side (Richard Ogle: Smart World).
