I had not thought of a live chat but that is a good idea if it could be set up.
As an overview how would it work? I have used chat on various websites and it has been a very helpful way to get help.
For example the chat facility on Papier. I used that to find out details about making one-off custom greetings cards.

The option to chat just pops up in the lower right corner, and if it is out of hours one can leave a message.
Yet that chat, as with others I have used, is one to one, so if a chat were done with a sponsored discussion it would need to be many to one, so maybe it would need to work by people sending a private message to the expert, then the expert does a copy and paste to the chat and then answers. Sort of "I have been asked ... then the question.
For example,
I have been asked what flowers can I grow as my garden is basically clay and I am not in a position to go digging it or digging anything in?
Though maybe just posting in a thread like this and the expert just replies as posts are made would have the same effect as maybe chat could not work other than one to one.
A thread would provide a permanent record of questions and answers.
I suppose that if a business finds it beneficial to have people available for one to one chat all day then maybe for a week for a special event having one of them on Gransnet for a week might be no problem, it need not be the same person all day, and it could indeed be two people, each a specialist in different topics. I have found the chat advisers at Papier to be very knowledgable and helpful.
I have used one chat facility on one website to order items, but others are order online oneself and the chat facility is just for advice, about any of the product, delivery options, how to use the ordering system.
As to being costly, the member of staff involved would otherwise be on the chat line, so cost neutral there possibly, and Gransnet would charge a fee. But the business might get some orders as a result, so basically a form of advertising. So we might never know whether they made a profit or a loss by doing it.
For a business that does not have someone on a live chat facility it might be a different situation, but they do often have email support or a telephone helpline.
I know that views vary on whether people watch things like advertisements on television or pop and put the kettle on, but television channels that are basically all advertising are still going, for example QVC.
One can even watch it on the web in the middle of the night if one wishes.
I remember once, years ago, I saw a cookery hour on one of the shopping channels, I forget which, and maybe they had had comments about a previous show, because the presenter started off by showing a glass jug with lots of metal spoons in it and a plastic bowl and he made a point of saying that when the picture shows them getting a spoonful to taste something being cooked that each time they get a clean spoon to dip in and then taste it and then put the spoon in the plastic bowl to go to washing later and not used again in that particular show.
