Ask HN: Under Challenged at Current Position – Need Advice

Hello HN! I am currently working as a C#/.NET dev and have been at my current company almost 2 years. This is my first position out college, and while I have learned a lot I am beginning to feel un-challenged, bored, and annoyed. I have relayed this all to my manager (who has only been here for 1.5 months), and I have gotten no feedback. I have also been waiting 5 months for a review (I first asked for it five months ago). The lack of focus/goals at any level in the company is what is most annoying (Aside from my almost 1 hour 45 minute round trip commute each day). All I really want is to work on software that helps others, keep learning, and work with other intelligent people (I previously worked with 2 other devs, but I am the only dev at the company again). I just feel like this position is stagnating, and I don't want to feel that way any longer. I'm not sure if I should begin looking for new jobs, or just stick it out and see how it plays out. Any advice is appreciated.
