Well, it does seem generic because of the simple web template style. This makes the site look almost like a standard blog. That isn`t a bad thing but what does it say? Let me ask about your goals with the site.
Are you trying to create a brand with Great Management?
Do you think professional managers (your target audience I assume) would relate better to a site that is branded?
How do you want the site to grow? If you are envisioning a go-to resource for managers that becomes a company of its own, you should consider a logo. If you`re cool with it staying a simple article directory, like a side project, it might not matter so much.
CraigsList has proven that a logo or any kind of personalized brand is not needed for success. But then Craigslist has no personality whatsoever, even more dry than newspaper classifieds. This works for them and I think is a rare instance.
On the other hand (speaking of newspapers), we can look at newspapers (paper and online) as an example. Their content, like yours, comes from various sources and is primarily text based. The personality comes from what is written, not as much how it is presented. But they still take a stance on who they are as the source. There is a logo, a look and feel to these news sources.
In my opinion, the reader will put more stock into a resource if it is presented in a way they respect. Most times, this means at least a logo. I think a logo will do you good.
But then again, I am a logo designer. :) And since you asked where to go, check out what I do
