If you're trying to collect some scientific data, then it absolutely could yield useful information. But for the average hobbyist I doubt it would be meaningful...just unnecessary handling that increases the chances of the tarantula getting injured or the human being bitten/ haired. And the metabolic rates of tarantulas are so incredibly slow that meaningful changes would probably be difficult to observe unless one had a very sensitive scale and weights were taken at certain times (before, after a molt, while gravid, etc). That being said, an animal's weight over time can be a useful indicator of its health. But in this case there isn't really anything to compare it to for reference.
