Worth writing in?
Embedded Computer Systems reads as low-competition at first glance, but the full list shows thin reader activity — the median book has just 0 reviews. Weak incumbents here usually mean weak demand, not an open door. Vacancy score 81.0/100. Data caveat: this category's list-page review counts may understate actual totals — treat the numbers as a conservative floor pending spot checks.
