<image>As shown in the figure, the line $$y=k_{1}x+1$$ intersects the hyperbola $$y= \dfrac {k_{2}}{x}$$ at the points $$P(1,m)$$ and $$Q(-2,-1)$$. 
$$(1)$$ Find the value of $$m$$; 
$$(2)$$ If $$A_{1}(x_{1},y_{1})$$, $$A_{2}(x_{2},y_{2})$$, and $$A_{3}(x_{3},y_{3})$$ are three points on the hyperbola, and $$x_{1} < x_{2} < 0 < x_{3}$$, directly write the inequality relationship among $$y_{1}$$, $$y_{2}$$, and $$y_{3}$$; 
$$(3)$$ By observing the graph, directly write the solution set of the inequality $$k_{1}x+1 > \dfrac {k_{2}}{x}$$.
