(Reuters) -Twitter Inc shares sank 11% in post-market trading on Thursday as it offered tepid revenue guidance for the second quarter, warned of rising costs and expenses and said user growth could slow as the boost seen during the coronavirus pandemic fizzles.

The social media company posted revenues and user numbers mostly in line with analyst estimates in stark contrast to the better performing digital ad firms like Facebook Inc and Alphabet Inc's.
