I think that more needs to be done to encourage subscriptions to the 'silver' level at £10/month or so via adding improvements mentioned above; eg better 'fundamentals' almanac etc. Many thousands of small investors would be able to afford that whereas they are likely to baulk at greater amounts unless they are an active professional or 'day trader' who needs L2 and can afford it.
Attracting a lot more people to 'silver' would also help to cut down the percentage of silly, abusive or multiple posts imho.
