NEW YORK (TheStreet) -- Twitter is expected to make its public debut on Thursday and trade under the ticker symbol "TWTR." TheStreet's Jim Cramer said he likes Twitter. The company's incredible revenue growth will eventually lead to positive earnings per share, he said.

He's not worried about the business per se, but is concerned about investor sentiment, which seems incredibly bullish leading up to the IPO. 

Remember the bullish enthusiasm that surrounded Facebook (FB) on its IPO? Cramer fears investors may be willing to chase Twitter at any price just to get in on the action. FB is now a holding in Cramer's charitable trust, Action Alerts PLUS.

Twitter does have one problem, Cramer said: international ad sales. Cramer pointed out Twitter has largely failed in monetizing this segment of its business, which will be very important going forward. For perspective, Facebook and Google (GOOG) derive roughly 50% of their business from overseas.

Cramer said he would not advise chasing Twitter shares if the valuation climbs north of $20 billion.
