I do use Twitter but, I admit, not in the most "Twitter-ish" way. In other words I don't put any effort into boosting my followers and I "mix-up" my interests in the same account (some of my political re-tweets must drive my FI followers mad - if they ever read them, more of this below). In other words, I follow who I'm interested in and I tweet what I'm interested in. I only access my timeline about once a day - more often if there is a breaking news story that I'm curious about as I find it particularly useful for up to the minute information and opinion, and I don't tweet on anything like a regular basis.
Another interesting article about Twitter this week mentions a further effect that comes into play when it is used in the conventional way - i.e. the way aimed at gaining you the most followers by following lots of people yourself - and that is a situation arises such that:
"genuinely tending to the tweets of more than 200 people becomes impractical (and unenjoyable) ..... with everyone sending out tweets few people have the time or energy to read or act upon." (Andrew Smith)
Over-enthusiastic "following" which is part of the essence of proactive Twitter usage, means you are less likely to actually see the quality tweets that you are really interested in, because your time-line will be full of stuff you're not really interested in .
In many ways this emphasis on quantity rather than quality reminds me of the investing sin of diworsification - i.e. holding so many funds/stocks that any inherent quality/value in the portfolio is lost or watered down by the fact that it makes up such a small part of the whole.
The subject of this week's Portfolio Clinic in Investor's Chronicle is a case in point. The investor holds 46 funds, and as the commentators point out, he may as well be holding a global index fund at far less cost and trouble. But also, as with the Twitter "too much noise" effect any quality brought to his portfolio by actively choosing funds is drowned out by, and buried in, the quantity of assets he owns.
"46 is far too many. Apart from being a large number to manage, research and review, there is the potential for overdiversification or 'diworsification' - where a portfolio is spread so thinly that any outperformance is too small to be noticeable." (Danny Cox).
The obvious answer for us ordinary investors to the issue of diversification in equities is, of course, to hold a global tracker and not to look at it too often. This incidentally is also perfect advice for the ordinary Twitter user (celebrities excluded) who is determined to get their follower count as high as possible. Follow everyone, (if you're really dedicated to the task you can even use software to do the job for you) and don't even try to asses the quality of what they say. Trying to mix quality with quantity in either stocks or Twitter is a self-defeating exercise.
