Non-PRO Japanese to English Marketing Telecom(munications)

もともと空気を読んで行間を推し量るタイプのコミュニケートを身上とする日本人ならではの感覚ですが、草食化して女の子に告白も恥じらうへタレな男子には切実な機能かもしれません。

I believe it is talking about the original purpose of 言花 (http://www.nec.co.jp/press/ja/0603/0304.html) but I can't quite get the translation to make sense. So far I've got is the literal translation of the various words and they aren't fitting together very well.


I think I have a translation for the second half. Either:

"these features may compel young men to attempt to make young women blush"

OR

"these compelling features are useful for people who may be bashful, such as young men confessing to young women"


But then, neither of those contain the タレな of the source text (I think).

Could anyone offer a) a translation of the full sentence, and b) advice for future situations like this where the translation just won't come to you.
