You may or may not have had a look on this. At some point I found a top list of recent most popular keywords in internet searches (I don’t know how frequently the list is updated, but it seems it doesn’t change that often). Predictably, this kind of list doesn’t depart too much from what people use internet for, namely getting obcessed with famous people (good mention of politics, music and sports), or looking for porn (though it is much less true than one might think apparently). That, and horoscoping with reality and shopping.
But what’s amazing, is a bunch of other things internet is used for. Wheather information, or getting directions /organising travels probably are a current major source of use. Good deal.
Strikingly, plants flowers do belong to the top 500 key words list, and I would not have bet. First, thinging with pumpkins, there come the plants. Easy, that’s for a major fest in fall. But there are quite other botanically enclined searches. Flowers for mariage or meaning of flowers (2 to 4 occurences)… That’s indicative that plants flowers have a great deal to do with social relationships, and not the least. Ones that count. Or ones for festing. And that, I find it interesting. Not sure that’ll change people’s mind as to why it is important to keep botany alive, but still, maybe that could help.
